Novel processes for the preparation of bicyclic aminoalcohols

摘要

The present invention provides a process for the preparation of a bicyclic aminoalcohol which comprises reacting a starting compound, nopinone (I), with XCH<Sub>2</Sub>COOR<Sup>1</Sup> wherein X is halogen, and R<Sup>1</Sup> is alkyl, in the presence of an additive and a base to produce a compound (II), converting it to oxime derivative (III), and reducing it with an aluminum hydride.
