C2 对称的基于 pyrrolidine 的 tetraamine,从商业地开始材料可得到,为到特别到 chalcones 的 nitroalkenes 的酉同类的不对称的迈克尔增加的显示出的好催化活动。反应继续了在好收益并且以一种高度选择的方式给相应产品。
C2-Symmetric pyrrolidine-based tetraamine, available from commercially starting materials, showed good cata- lytic activity for asymmetric Michael additions of ketones to nitroalkenes especially to chalcones. The reactions proceeded to give the corresponding products in good yields and in a highly selective manner.
