Abstract

A stereodivergent total synthesis of the Delta(13)-9-isofurans has been developed. The four core substituted tetrahydrofurans were prepared by the Sharpless asymmetric epoxidation and Sharpless asymmetric dihydroxylation followed by cascade cyclization. The relative configuration at C-8 was inverted by oxidation followed by immediate L-Selectride reduction. The relative configuration of the C-15 diastereomers was assigned by (S)-Binol/LAH/EtOH reduction of the corresponding enone. This synthesis of the Delta(13)-9-isofurans will provide sufficient material for further investigation of their biological activity.

摘要

已开发出一种立体发散性全合成Δ(13)-9-异呋喃的方法。通过夏普莱斯不对称环氧化和夏普莱斯不对称双羟基化反应,随后进行串联环化反应,制备了四个核心取代的四氢呋喃。通过氧化,然后立即用L-选择氢化物还原,使C-8处的相对构型发生反转。通过用(S)-联萘酚/氢化铝锂/乙醇还原相应的烯酮,确定了C-15非对映异构体的相对构型。这种Δ(13)-9-异呋喃的合成将为进一步研究其生物活性提供足够的材料。
