4-addition reactions of alkanesulfonamides were developed on the ‘product base’ strategy. Alkanesulfonamides reacted with α,β-unsaturated amides in good to high yields with good to high diastereo- and enantioselectivities using a chiral alkaline metal amide. To our knowledge, this is the first example of a catalytic asymmetric C–C bond-forming reaction using an alkanesulfonamide without any activating group
链烷磺酰胺的催化不对称 1,4-加成反应是基于“产品基础”策略开发的。使用手性碱金属酰胺,链烷磺酰胺与 α,β-不饱和酰胺以良好至高产率以及良好至高的非对映选择性和对映选择性反应。据我们所知,这是使用烷烃磺酰胺在其 α 位没有任何活化基团的催化不对称 C-C 键形成反应的第一个例子。
