A series of saccharide-derived bifunctional tertiary amine-thioureas for the asymmetric Michael addition reaction have been designed and synthesized. The addition products between malonates and various nitroolefins were obtained in high yields (up to 99%) and excellentenantioselectivities (up to 99% ee).
已经设计并合成了一系列用于不对称迈克尔加成反应的糖衍生的双官能叔胺
硫脲。
丙二酸酯和各种硝基烯烃之间的加成产物以高产率(高达 99%)和优异的对映选择性(高达 99% ee)获得。
