catalyst, the asymmetric [3+2] annulation of Morita–Baylis–Hillman carbonates with cyclic 1‐azadienes proceeded smoothly under mild conditions to give various enantiomerically enriched cyclopentene derivatives bearing three consecutive tertiary stereocenters and a sulfamate moiety in moderate to excellent yields with moderate to excellent enantioselectivities and excellent diastereoselectivities.
使用双官能手性膦作为催化剂,森田-贝利斯-希尔曼碳酸盐与环状1-氮杂二烯的不对称[3 + 2]环化在温和条件下顺利进行,得到了具有三个连续的三级立体中心的各种对映体富集的环戊烯衍生物。氨基磺酸盐部分,具有中等至优异的收率,具有中等至优异的对映选择性和出色的非对映选择性。
