✦ Synopsis

R,R)-Zr(salen) complex was found to serve as an efficient catalyst for asymmetric Baeyer-Villiger oxidation of pro-chiral and racemic ketones using urea•hydrogen peroxide as the terminal oxidant: for example, high enantioselectivity of 87% ee was achieved in the Baeyer-Villiger reaction of 3-phenylcyclobutanone.

A cationic Co(III)(salen) complex of cis-b-structure was found to serve as an efficient catalyst for asymmetric Baeyer-Villiger reaction of 3-substituted cyclobutanone using hydrogen peroxide as a terminal oxidant. Good enantioselectivity up to 78% ee was achieved.
