[reaction: see text] Total synthesis of hyacinthacine A(1) and its epimer at C3 is described. The synthesis includes a stereocontrolled carboazidation of a chiral allylsilane as a key step. C-Si bond oxidation and reduction of the azide, with ring-closure, complete the total synthesis, which establishes the absolute configuration of 3.
[反应:见正文]描述了葫芦素A(1)及其在C3的差向异构体的全合成。该合成包括手性烯丙基硅烷的立体控制碳叠氮化作为关键步骤。C-Si键氧化并还原叠氮化物,并进行闭环反应,完成了整个合成过程,从而确定了3的绝对构型。
