by which means lactams that are precursors in the synthesis of diverse natural and synthetic products, including pyrrolidinone compounds such as lactacystin, pramanicin, kainic acid, statine, AHPPA, and rolipram, are produced.
内酰胺,内酰胺库和一种有效的合成内酰胺的方法,包括一种&ggr;-内酰胺,在这种方法中,具有一般结构(I)的a-重氮乙酰胺在促进分子内C-H插入的条件下反应,例如在存在铑盐如Rh2(OAc)4的情况下,通过这种方法产生了内酰胺,这些内酰胺是合成各种天然和合成产物的前体,包括吡咯烷酮类化合物,如乳酸胶蛋白酶、普拉曼霉素、卡因酸、斯塔丁、AHPPA和罗利普拉姆。
