  A Catalytic Asymmetric Synthesis of 11-Deoxy-PGF_1α Using ALB, a Heterobimetallic Multifunctional Asymmetric Complex

  摘要：

  A catalytic asymmetric synthesis of 11-deoxy-PGF(1 alpha) has been achieved using a cascade Michael-aldol reaction as a key step. This cascade reaction was efficiently promoted by a catalytic use of AlLibis[(S)-binaphthoxide] complex (ALB) to give the three-component coupling product at room temperature in 92% ee and in 84% yield. The three-component coupling product was then converted to (+)-11-deoxy-PGF(1 alpha) through several steps, including an oxidative decarboxylation, an aldol reaction, and a Wharton reaction. Moreover, the racemic enone, 20 was transformed into 21, the three-component coupling product, a potential intermediate for PGF(1 alpha), in 97% ee and in 75% yield through catalytic kinetic resolution.
