Highly Enantioselective Intermolecular Stetter Reactions of β-Aryl Acceptors: α-Ketoester Moiety as Handle for Activation and Synthetic Manipulations
摘要:
The use of beta,gamma-unsaturated-alpha-ketoesters in the intermolecular Stetter reaction furnishes 1,2,5-tricarbonyl compounds in high yield and excellent enantioselectivity. The alpha,delta-diketoesters generated using this methodology serve as useful synthetic building blocks via chemo- and diastereoselective transformations.
