摘要:
This invention relates to new nematic liquid crystal substances for electro-optical components.The object of this invention is to create substances for electro-optical components combining chemical and thermal stability with low melting and high clear points at low operational voltage, as well as to processes for their production.It has been found that new liquid-crystal trans-6-n-alkyl-decalin-2-carbonic acid ester of the general formula ##STR1## can be introduced into electro-optical components. These substances are produced by the catalytic high-pressure hydrogenation of 6-n-alkylnaphthalene-2-carbonic acids, separation of the trans-isomers by distillation, and esterification with the corresponding hydroxy compounds of the acyl chlorides obtained through reaction with thionyl chloride.

摘要:
Described is a process for augmenting or enhancing the aroma or taste of a foodstuff or chewing gum comprising the step of adding to a foodstuff or chewing gum an aroma augmenting or enhancing quantity of a product comprising a major proportion of compounds defined according to the structure: ##STR1## wherein the dashed line is either a carbon-carbon single bond or a carbon-carbon double bond and each of the R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.6 and R.sub.7 represents hydrogen or methyl with the proviso that one of R.sub.1, R.sub.2, R.sub.6 and R.sub.7 is methyl and each of the other of R.sub.1, R.sub.2, R.sub.6 and R.sub.7 is hydrogen and R.sub.3 and R.sub.4 are not both methyl; wherein R.sub.5 represents C.sub.1 -C.sub.4 produced according to the process of reacting an alkyl acrylate compound with a methyl cyclopentadiene in the presence of or in the absence of catalyst to form a norbornane carboxylate ester-containing mixture and using the resulting mixture for its organoleptic properties or further reacting the mixture with hydrogen to produce a norbornane carboxylate-containing mixture and using that mixture for its organoleptic properties in augmenting or enhancing the aroma or taste of footstuffs or chewing gums.
摘要:
A soluble, chiral, rhodium-containing catalyst which permits the catalytic reduction of prochiral 3-acyl-1-2-alkoxyethyl)-4-phenyl-2-imidazolinones to chiral 3-acylimidazolidinones with a substantial excess of the desired S optical isomer. The 3-acylimidazolidinones may in turn be substantially converted to levamisole, the S isomer of tetramisole. The resolution of tetramisole to remove the R isomer is thus avoided.

摘要:
Provided is a process for the preparation of certain 1,4-bicyclo[2.2.2]octane derivatives. The new synthetic procedure involves treating 1,4-dimethylene cyclohexane with an oxidizing agent in the presence of a transition metal catalyst to afford an oxo-substituted bicyclo[2.2.2]octane species. This intermediate structure can then be further derivatized. The processes of this disclosure thus affords a novel and simplified means for the commercial production of a wide variety of bicyclo[2.2.2]octane derivatives.
