oxonium ylide formation/[2,3] sigmatropic rearrangement in a one-flask operation and in a highly diastereoselective manner. The methodology has been demonstrated in a concise synthesis of the anti-HIV agent hyperolactone C.
带有烯丙基醚官能团的α-重氮-β-酮酸酯经历高度立体选择性的Ru-卡宾催化的烯烃交叉复分解,然后在Rh(2)(OAc)(4)催化的氧鎓叶立德形成/ [2,3]σ重排中一瓶操作,并且具有非对映选择性。该方法已在抗HIV药物高内酯C的简明合成中得到证明。
