Tricyclic core of manzamine B was successfully synthesized through asymmetric Diels–Alder reaction and RCM strategy. Cr–salen–F complex was found to be the most effective catalyst in DA reaction of aminodienes with heterocyclic dienophiles to give up to 97% ee. In the construction of 11-membered ring by RCM, first-Grubbs cat. gave better stereoselectivity.
通过不对称Diels-Alder反应和RCM策略成功合成了曼扎明B的三环核。发现Cr-salen-F络合物是氨基二烯与杂环二烯亲和物的DA反应中最有效的催化剂,其ee含量高达97%。在由RCM建造的11元环中,第一格拉布斯猫。具有更好的立体选择性。
