Catalytic asymmetric Nazarov reactions promoted by chiral Lewis acid complexes.

Varinder K Aggarwal1, Andrew J Belfield.   

Abstract

Divinyl ketones bearing alpha-ester or alpha-amide groups undergo Nazarov cyclizations to give cylopentenones using copper-bisoxazoline Lewis acid complexes with moderate to good ees. [reaction: see text]
