Abstract

Chiral dihydropyridone derivatives 3 are obtained in high yields and with good enantioselectivities by the title reaction of aldimines such as 1 with Danishefsky's diene 2. 6,6'-Dibromo-1,1'-binaphthol complexes with Group 4 metals serve as catalysts; zirconium proved to be especially effective. © 1998 WILEY-VCH Verlag GmbH, Weinheim, Fed.
