A highly enantioselective organocatalytic protocol for conjugate addition of new nucleophilic carbonylmethyl 2-pyridinylsulfone to enals has been developed in good yields and with high enantioselectivities. The resulting Michael adducts are versatile building blocks for a variety of organic transformations.
已经开发出高收率和高对映选择性的高度对映选择性的有机催化方案,该方案用于将新的亲核羰基甲基2-吡啶基砜共轭添加到烯醛中。所得的迈克尔加合物是用于各种有机转化的多功能构建基块。
