building block: A concise enantioselective synthesis of the diazatricyclic core of sarain A has been accomplished. The novel strategy relies upon the versatile chiral building block (R)‐1 (see scheme), and features a tandem Horner–Wadsworth–Emmons–aza‐Michael reaction, an intramolecular Michael reaction, and the diastereoconvergent formation of the third ring. Diazatricyclic core 2 possesses all of
一个强大的手性结构单元:萨林A的二氮三环核心的简洁对映选择性合成已完成。新颖的策略依赖于通用的手性结构单元(R)-1(请参见方案),并具有串联的Horner-Wadsworth-Emmons-aza-Michael反应,分子内迈克尔反应和非对称会聚第三环的形成。二氮杂三环核2具有所有必要的功能,可以进一步加工成沙林A。
