The synthesis of cephalotaxine ring analogues 10 was achieved by two successive intramolecular palladium-catalyzed reactions of 12 via 11, namely an allylic amination and a Heck reaction. The substrates 12 were obtained by alkylation of primary amines 13 with tosylates 14.
头孢他辛环类似物10的合成是通过两个连续的分子内钯催化的12至11反应,即烯丙基胺化和Heck反应。通过伯胺13与甲苯磺酸酯14的烷基化获得底物12。
