Organocatalytic asymmetric conjugate addition of nitroalkanes to vinyl sulfone mediated by cinchona alkaloid-derived thiourea catalyst afforded the desired Michael product with good enantioselectivity. The described method, in combination with ready desulfonation, represents a novel approach to access α-alkylated chiral amines.
由金鸡纳生物碱衍生的硫脲催化剂介导的将硝基烷烃有机催化不对称共轭加成到乙烯基砜中,得到具有良好对映选择性的所需迈克尔产物。所描述的方法与现成的脱硫方法相结合,代表了一种新颖的方法来获得α-烷基化的手性胺。
