The asymmetric catalytic aza-Morita–Baylis–Hillman reaction of N-sulfonated imines with α,β-unsaturated ketones has been successfully conducted by using chiral bifunctional phosphine amides as catalysts. A series of new chiral bifunctional phosphine amides were designed, synthesized, and systematically studied for this asymmetric reaction. The corresponding aza-MBH adducts were obtained in good yields
N-磺化亚胺与α,β-不饱和酮的不对称催化氮杂-Morita-Baylis-Hillman反应已通过使用手性双官能膦酰胺作为催化剂成功进行。针对该不对称反应,设计,合成和系统地研究了一系列新的手性双官能膦酰胺。在温和的条件下,获得的相应氮杂-MBH加合物收率良好(75–99%),对映体过量非常好(51–95%ee)。
