CATALYTIC COMPOSITIONS AND METHODS FOR ASYMMETRIC ALLYLIC ALKYLATION

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 catalyst...

Summary: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. Des complexes d'une classe sélectionnée de ligands chiraux avec du molybdène, du tungstène ou du chrome, de préférence du molybdène, sont efficaces en tant que catalyseurs dans l'alkylation hautement éniantosélective et régiosélective de substrats allyliques. Ces compositions offrent une alternative polyvalente et bon marché aux catalyseurs existants.
