【 摘 要 】

Two heterogeneous catalysts 4 and 5 and three homogenous complexes 1-3 were prepared and used for enantioselective Baeyer-Villiger (B-V) oxidation of prochiral cyclobutanones. Among the prepared catalysts, the supported ones showed better enantioselectivity, good thermal stability and negligible loss of activity over consecutive recycling offset by lower chemical yield.
