Provided herein is an optically active alcohol having a silyl group, stannyl group, or halogen atom at the y-position, selected from compounds represented by the general formula [I],
the general formula [II],
the general formula [III],
and the general formula [IV],
(where, R denotes a C1-C10 substituted or unsubstituted alkyl group or substituted or unsubstituted phenyl group: A denotes a silyl group represented by
a stannyl group represented by
or a halogen atom; R1, R2, and R3 are substituted or unsubstituted C1-C10 alkyl groups or substituted or unsubstituted phenyl group, which may be the same or different, provided that in general formulas [III] and [IV] A does not represent a stannyl group or halogen atom; a process for producing the same, and a process for resolving the optically active alcohol into isomers of high optical purity.
本发明提供了一种在 y 位上具有硅烷基、链烷基或卤原子的光学活性醇,该醇选自通式 [I] 所代表的化合物、
