Treatment of thiolesters with zinc reagents in the presence of Ni(acac)2 provided a variety of functionalized ketones in good yields. This new protocol was successfully applied to the synthesis of (+)-biotin to allow for a practical installation of the carboxybutyl chain.
在Ni(acac)2的存在下用锌试剂处理巯基酯可提供多种功能化的酮,收率很高。此新协议已成功应用于(+)-生物素的合成,以允许实际安装羧基丁基链。
