Cu(I)-Catalyzed Reductive Aldol Cyclizations: Diastereo- and Enantioselective Synthesis of β-Hydroxylactones
摘要:
Copper bisphosphine complexes catalyze the intramolecular reductive aldol reaction of alpha,beta-unsaturated esters with ketones, affording five-and six-membered beta-hydroxylactones in high stereoselectivities. Utilization of chiral nonracemic bisphosphines render the cyclizations enantioselective.
