for high enantioselectivity and diastereoselectivity compared with those obtained from common trans-pyrrolidine catalysts. Not only configurational but also polymeric effects contribute to the high diastereoselectivity and enantioselectivity. Polymer catalysts were also successfully applied in a continuous-flow process. Acceleration of the reaction rate, an increase in diastereoselectivity, and an improvement
与从普通的反式-吡咯烷催化剂获得的那些相比,开发了聚合物负载的顺式-吡咯烷催化剂,其允许高的对映选择性和非对映选择性。不仅构型效应而且聚合效应也有助于高非对映选择性和对映选择性。聚合物催化剂也成功地应用于连续流工艺中。与间歇式系统相比,在连续流操作中观察到反应速率的加快,非对映选择性的增加和耐久性的提高。
