摘要

An environment-friendly L-prolinamide catalyzed aldol reaction has been developed. The reaction exhibited broad substrate generality, and high yields with good diastereoselectivity were obtained for cyclic ketones. The simplicity of product isolation, usage of water as environmentally benign reaction medium, and the usage of cheap,readily available and recyclable catalyst make this process promising to be developed for large-scale preparation of β-hydroxyl ketones.
