that is not the question! The anti,anti configuration of the C7–C16 fragment of (+)‐neopeltolide is stereoselectively installed in an iterative sequence of catalyst‐controlled Si group and Me group transfers, even with mismatched selectivity in the former (Si=Me2PhSi, see scheme; TBS=tert‐butyldimethylsilyl).
匹配或不匹配,这不是问题!(+)-新油菜碱内酯的C7–C16片段的抗,抗构象被立体选择性地安装在催化剂控制的Si基团和Me基团转移的迭代序列中,即使前者的选择性不匹配(Si = Me 2 PhSi,请参见方案; TBS =叔丁基二甲基甲硅烷基)。
