CATALYTIC COMPOSITION BASED ON CHIRAL LIGANDS WITH MOLYBDENUM, TUNGSTEN OR CHROMIUM AND METHOD FOR ASYMMETRIC ALKYLATION OF ALLYLIC SUBSTRATES

摘要

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.
