O-Trityl oximino esters 1 undergo stannane-induced radical cyclization to regenerate an oxime function, affording oximino lactones 4; these can be converted into enamides (e.g. 11b), and such a transformation was used to make the natural product 14c.
O 型三苯甲基肟酯 1 在锡烷的诱导下发生自由基环化反应,重新生成肟功能,从而得到肟内酯 4;这些内酯可转化为酰胺(如 11b),这种转化被用于制造天然产物 14c。
