| titleOfInvention | Process for producing optically active alcohol |
| abstract | The process for producing an optically active alcohol of the present invention comprises allowing n (A) an optically active amino alcohol represented by the general formula (I) ##STR1## (R 1 is an aryl group, R 2 is a lower alkyl group, R 3 is a hydrogen atom or a lower alkyl group, and the carbon atoms having a mark * are each an asymmetric carbon atom) and an acid, or a salt of the optically active amino alcohol (I) and an acid, n (B) a metal borohydride, and n (C) at least one member selected from the group consisting of water, sulfides, cyclic ethers, ethers of mono alcohol to react with n a prochiral ketone represented by the general formula (II) ##STR2## [R 4 and R 5 are different and each a lower alkyl group, an aryl group, an aralkyl group or a 2-substituted-1-triazoleethylene group represented by the general formula (III) ##STR3## (R 6 is a halogen- or haloalkyl-substituted or unsubstituted phenyl group or a cycloalkyl group)]. n According to the present invention, the optically active alcohol (IV) can be obtained with good efficiency and a high optical purity. Therefore, the present process is advantageous in industrial application, in particular. |
