free alcoholic −OH unit leads selectively to the formation of tetrahydrofuranobenzopyran ring system. This approach has been used for the regio- and stereoselective synthesis of xyloketal D, xyloketal G, and the related natural product alboatrin.
一种新的高效的一锅式甲硅烷基化的去甲硅烷基化-金催化的环异构化反应,该反应包含有甲硅烷基保护的酚-OH和游离的醇-OH单元,可以选择性地导致四氢呋喃并苯并吡喃环系统的形成。该方法已经用于木酮基D,木酮基G和相关天然产物alboatrin的区域和立体选择性合成。
