For the first time, a catalytic asymmetric Henry reaction of 1H-pyrrole-2,3-diones was achieved with a chiral bifunctional amine-thiourea as a catalyst possessing multiple hydrogen-bond donors. With this developed method, a range of 3-hydroxy-3-nitromethyl-1H-pyrrol-2(3H)-ones bearing quaternary stereocenters were obtained in acceptable yield (up to 75%) and enantioselectivity (up to 73% ee).
首次实现了以具有多个氢键供体的手性双功能胺-硫脲为催化剂,对1H-吡咯-2,3-二酮进行催化不对称亨利反应。通过这种开发的方法,获得了一系列带有季碳立体中心的3-羟基-3-硝基甲基-1H-吡咯-2(3H)-酮,产率(高达75%)和对映选择性(高达73% ee)均可接受。
