Optically isomers inosites, can be demonstrated and method for the production of an optically active compound

摘要

the invention concerns a method for the production of optically active hydroxycarboxylic acids or their esters diolen or fully the steps: $a (a) to establish a second connection or 1l 1.2. 56 - di - o - cyclohexyliden - chiro - inositol from a first connection or 1l chiro - inositol as asymmetric parent compound; $a (b) to introduce a sterisch hindernden group in one of the 3 and 4 positions and an asymmetrical reactive group in the other position in the second link; $a and $ a (c) reducing the compound obtained, $a and thus manufactured compounds.
