Since with such a reduction of the carbalcoxy group the configuration is usually maintained the dioxyacid (VI) should have "cis-treo" configuration.

The Raman spectra of the compounds were taken in the liquid phase and in carbon tetrachloride solution. From the data obtained, the following conclusions were drawn: The alcohols form intermolecular hydrogen bonds in solution (bands split up into Card 1/3 lines in the3160-3530 cm- I range). These hydrogen bonds do not Optical Investigation of the Conformations of SOV/62-59-9-26/40 Cis and Trans-10-dimethyloyclohexanols stem from the hydroxyl group. In the_liquid phase complexes are formed by hydrogen bonding of the OH group (continuous bands in -Uie 3600 and 3614 am-I region)o 'The hydroxyl groups generally have a similar position (equatorial) in the associated complex. Thus, in (I) their position is cis-la3a and in (11) trans-lale. Their position was determined at cis-le3a in (1) and trans-la3e and trans-le3a in (II) (equatorial and equatorial-axial), relative to the CH -group outside the hydrogen bond as the largest substitueRt. If one disregards the nomenclature of these configurations and conformations by reason of their formation, and regards solely their real structure, deduced from their physical properties, as well as taking into account the transformation rule by Barton and Hassel (the configuration is determined by the position of the largest substituent) one would have toredefine the cis-la3a conformation of (I), the form predominant in associated molecules, of (I), and also the Card 2/3 Optical Investigation of the Conformations of SOV/62-59-9-26/40 Cis and Trans-lt3-dimethylGyClohexanols trans-la3e conformation of (II).

It was shown that under the influence of diluted sul- M phuric acid solutions, the alkylidene acetones and the oxide of 3-methylhepten-3-one-2 isomerize into the a-diketones and also hydrolize into the corresponding keto glycols. The ultra- violet absorption spectra of the oxides of ethylidene-, propylidene-, trans-n- and trans-isobutylidene-, isovalerylidene acetone and of 3-methylhepten-3-one-2 were recorded. All these acetones have one and the same absorption band at 285-290 mg, which refers to the carbonyl group (Figs 1-2). There are 2 figures and 27 references, 12 of which are Soviet.

The Raman spectra of both these substances were taken by means of the Soviet 3 prism spectrograph ISP-51 with a central chamber and the Hilger spectrograph Ye612 in the liquid phase. The exciting frequency 4358 A stemmed from a mercury lamp. The measured frequencies are specified. The presence of frequencies in the region of the triple bond (2096, 2111 am-1) in the spectra of both substances points to the fact that they still contained residues of the athinyl compound utilized for their synthesis. i - C frequencies showed that the oxidation of acetyl cyclo- hexene was incomplete and that the oxidation product is a Gard 1/4 mixture from acetyl Cyclohexene and its oxide. The oxide, how- 67914 Optical Investigation of the Conformations of Aostyl BOV/20-129-5-21/64 Cyclohexone and Its Oxide over, is clearly predominant. It was electronographically confirmed (Refe 2,3) that the carbon atoms of the double bond C, and C2 are placed on or approximately on the same planso The molecule exhibits half-chair-shaped (polukreelo- vidnyy) conformations (Ref 4) (see Scheme). The vhlencies are quasi-equatorial (e1) and quasi-axial ( at) at the atoms C3 and CO whereas they are equatorial (e) and axial (a) at tK C4 and 05. Since the half-chair-shaped confirmation of cyclo- hoxene is energetically by 2-7 kcal/mol more advantageous and since the rules established by Barton and Khaseell (Rof fl are evidently still valid for substituted cyclohexenes, the half-chair-shaped confirmation in acetyl cycloboxene is apparently predominant. In this connection, the acetyl group is placed on the plane of atoms C,C 2C3C6 or on an approximated plane (see Scheme). There are no reasons for denying the con- servation of the acetyl group position in the case of conversion (I)# (II). The carbonyl group frequency is divided into 1663 and 1672 cm-1. The ethylene bond frequency is practically not Card 2/4 divided into a doublet. The authors are inclined to assume that 67914 optical Investigation of the Conformations of Acetyl BOV/20-129-5-21/64 Cycloh*xene and Its Oxide the division of the oarbonyl frequency is to be explained by the possible double position of carbonyl with respect to the ethylene formation CaC of the ring, namelyg the ois-oid position ((I)#(II)) and the trans-oid position ((14# (IV)) (see Scheme). The oscillation frequency of the ethylene bond remains practibally unchanged. The oxidation of the acetyl cyclohexene on the double bond leads to the formation of a 3-maimbered: oxide ring /-\C, whose C-C-bond belongs to the 6-membered carbon ring. The half-chair-shaped conformation of the 6-membered ring.is-oon- served in the acetyl cyclohexene oxide (Ref 9). If the above- mentioned position of the acetyl group is conserved, the oxygen atom of the 3-membered ring (see above) is placed on a plans which is peryendicular~-to the plane C 1C2C 3C6* The above con- cepts were concreted by optical data supplied by the authors.' It was finall confirmed that acetyl cyclohexene oxide exists in cie oid (V~*ft(VI) and trans-oid (VII)V-:~(VIII) conformations.

All four alcohols have different melting points* :..Their structures were studied by their Raman spectra recorded on the 'USSR speotrograph of the type ViCTI-51 (ISP-51), and on an E612 Hilger spectro- graph. It is concluded from the data (Table 1) that a hydrogen bond exists between the hydroxyl group of these alcohols in liquid state and the oxygen atom of the oxide ring. This is confirmed by the fact that the 0 - H fre- quency is a blurred narrow band_yhioh is quite different in the two trans-. -ib omers.

B103/B208 while the liquid (II) has the intramolecular bond. This assumption was confirmed optically. In a considerable part of the molecules of (II) in the liquid phase the O-H group is released from the intramolecular H-bond and enters the intermolecular H-bond. The threo-isomer is thus partly converted to the erythro-isomer, or to an isomer having a similar position of the oxide ring as the erythro-isomer. The conversionof the erythro.- -isomer th the threo-isomer can hardly 6 confirmed op .tically in the case of'(I)., The authors conclude from these facts that the two types of H-boild represent the most important stabilizing factors in the case of erythro-threo-isomerism. The energy of the H-bond is not high (- 3 kcal/mole). These bonds therefore cause a considerable difference of the mentioned isomerism in crystalline state, but not in liquid or super- cooled-liquid state. The intramolecular bonds are, as a rule, not destroyed in 20% solutions of these alcohols in M 49 which was also optically confirmed. The complexes of (I) and (III) with several members, which are associated by the intramolecular H-bond, are destroyedt while dimeric complexes are preserved, and monomers are formed.

Vvedeniye dioksiatsetonovoy bokovoy tsepi metodom gidratatsii atsetilenovykh spirtov) PERIODICAL: Zhurnal obshchey khimii, 1959, Vol 29, Nr 3, PP 735-744 (USSR) ABSTRACT: The authors earlier described (Ref 1) the bromohydrin-, di- bromoketol- and glycide method of introducing the oxidized side chains into the cyclic compounds. They were likewise interested in the introduction of the dioxyacetone side chaing which is characteristic of some hormones, by the hydration of acetylene alcohols. Although after the completion of their investigations some reports appeared on the synthesis of the simplest cortisone analogues, in which the same method of introducing the above chain had been applied, their investiga- tion results still had to be published, inasmuch as the yields of the initial products obtained in the latter investigations mare higher, than had been those published according to Card 1/3 references 2-4. At first the dimethyl ethynyl carbinol (1), SOV/79-29-3-3/61 Synthesis of the Simplest Analogues of Corticosteroids. VII. Introduction of the Dioxyacetone Side Chain by the Hydration Method of Acetylene Alcohols which was obtained according to Favorskiy's reaction by conden- sation of the acetylene with acetone (Ref 5), was used an an initial product. In the hydration of carbinol (I) in the presence of sulphurio mercury, the dimethyl acetyl carbinol (H) (Ref 6), which is transformed into bromo acetyl dimethyl carbinol (III) by dioxane bromidep results in a high yield. In the action exerted upon this by alcoholic caustic potash lye, dimethyloxyacetyl carbinol (IV) (Scheme 1) is formed. On the reaction of the acetate of dimethyl acet 1 carbinol (V)(Ref 6) with dioxane dibromide, compound (Vl~ is formed, which in the action of alkaline caustic potash lye likewise passes over to (IV) and in acetolysis forms diacetate of (IV) - (VII) by the aid of potassium acetate in methanol. Also the following compounds were used as further initial products for this reaction: 1-ethynylcyclohexanol (VIII); 3,5-dimethyl-l-ethyn 1 clopentanol (XV); cis-2-methyl-1- ethynyloyclohexanol ~Xcx~ and 3,8-dimethyl-l-ethynyi- A5- tetrahydroindanol (XXVII). Their hydration with subsequent bromination and saponification of the forming a-bromo ketols Card 2/3 led to compoundsl which likewise contain the dioxyacetone SOV/79-29-3-3/61 Synthesis of the Simplest Analogues of Corticouteroids.
