3-amino-2-hydroxybornane derivatives, asymmetric Michael reaction using the same, and process for preparing optically active muscone utilizing Michael reaction

摘要

A 3-amino-2-hydroxybornane derivative represented by formula (I): ##STR1## wherein R represents a furfuryl group, a 1- methylpyrrolylmethyl group, or a benzyl group, is disclosed. The compound is useful as a ligand in an asymmetric Michael reaction, particularly for the production of an optically active muscone.
