Title:

CATALYTIC COMPOSITIONS AND METHODS FOR ASYMMETRIC ALLYLIC ALKYLATION

Document Type and Number:

WIPO Patent Application WO1999032225

Kind Code:

A9

Abstract:

Complexes of a selected class of chiral ligands with molybdenum, tungsten or chromium, preferably molybdenum, are effective as catalysts in highly enantioselective and regioselective alkylation of allylic substrates. Such compositions provide a versatile and low-cost alternative to existing catalysts.
