SYNTHESIS OF SOME DERIVATIVES OF CYCLOHEXANECARBOXYLIC ACID AND THEIR MESOMORPHOUS CHARACTERISTICS.

The cis- and trans-4-(4-methoxyphenyl)cyclohexane-1-carboxylic, cis-4-(4-methoxyphenyl)-cis-2-methylcyclohexane-1-r-carboxylic, and trans-4-(4-methoxyphenyl)-trans-2-methylcyclohexane-1-r-carboxylic acids and their 4-cyanophenyl esters were obtained.Unlik

The Preparation of Ethyl and Isopropyl Dienol Ethers and Dienol Pivalate Esters from Hagemann's Ester and its t-Butyl Analouge, and the Reactions of the Derived Ester Dienolates with Electrophiles

The preparation of ethyl 4-ethoxy-2-methylcyclohexa-1,3-diene-1-carboxylate, ethyl 4-isopropoxy-2-methylcyclohexa-1,3-diene-1-carboxylate, t-butyl 4-isopropoxy-2-methylcyclohexa-1,3-diene-1-carboxylate, ethyl 4-(t-butylcarbonyloxy)-2-methylcyclohexa-1,3-diene-1-carboxylate, and t-butyl 4-(t-butylcarbonyloxy)-2-methylcyclohexa-1,3-diene-1-carboxylate from Hagemann's ester and its t-butyl analogue in the presence of diethyl or diisopropyl sulfates and sodium hydride in dimethyl sulfoxide, or pivaloyl chloride and N,N,N',N'-tetramethylethylenediamine in tetrahydrofuran is described.The foregoing dienol ethers and esters are smoothly deprotonated by lithium diisopropylamide in tetrahydrofuran at -78 deg C to give corresponding ester dienolates, which react regiospecifically with a number of electrophiles, either α or γ to the alkoxycarbonyl group of the dienol ether or ester.A number of the products, which are generally obtained in good yields, have been hydrolysed to Hagemann's ester dirvatives substituted exclusively at C 1.
