A chiral phosphine-catalyzed asymmetric aza-Morita–Baylis–Hillman reaction between indole-derived sulfonyl imines and bis(3-chlorophenyl)methyl acrylate has been developed, giving the desired adducts in good yields and enantiomeric excess values along with the further transformations to polycyclic indoles such as dihydropyrido[1,2-a]indole and dihydropyrazino[1,2-a]indole skeleton.
已开发出吲哚衍生的磺酰基亚胺与丙烯酸双(3-氯苯基)甲酯之间的手性膦催化的不对称氮杂-Morita-Baylis-Hillman反应,得到所需的加合物,具有良好的收率和对映体过量值,并进一步转化为多环吲哚,例如二氢吡啶并[1,2- a ]吲哚和二氢吡嗪并[1,2- a ]吲哚骨架。
