The stereoselective synthesis of a C9–C19 fragment of the potent antitumor agent peloruside A is disclosed. The C11 stereogenic centre was created by a vinylogous Mukaiyama aldol reaction following Carreira's protocol, with excellent stereocontrol. The C13 stereogenic centre was introduced by a substrate controlled reduction. The C15 stereocentre was fashioned using Noyori's asymmetric transfer hydrogenation
公开了有效的抗肿瘤药鹅膏苷A的C9–C19片段的立体选择性合成。C11立体定向中心是由遵循Carreira规程的乙烯基Mukaiyama aldol反应形成的,具有出色的立体控制能力。C13立体异构中心通过底物控制的还原反应引入。C15立体中心是使用Noyori的不对称转移氢化法形成的,而Z-三取代的双键则是通过炔烃的区域选择性加氢氢化,然后使用Lipshutz的方法甲基化乙烯基锡烷形成的。C18手性中心是通过化学酶法引入的。
