摘要
报道了在手性磷酸作用下6-吲哚甲醇原位生成6-亚甲基-6H-吲哚,继而与异噁唑-5(4H)-酮发生不对称1,8-共轭加成反应.该反应实现了异噁唑-5(4H)-酮的对映选择性N-烷基化,以70%~83%的产率和61%~96%的对映选择性得到共轭加成产物.
A chiral phosphoric acid catalyzed aza-1,8-conjugate addition of isoxazol-5(4H)-ones to 6-methylene-6H-indoles formed in situ from 6-indolylmethanols has been developed for the first time.Notably,the remote stereocontrolled 1,8-addition of isoxazol-5(4H)-ones was featured by N-selectivity,affording aza-adducts in 70%~83%yields with 61%~96%ee.
