Mono thiomalonates (MTMs) are introduced as thioester enolate equivalents. Asymmetric organocatalyzed conjugate addition reactions to nitroolefins proceed under mild conditions to afford synthetically useful γ-nitrothioesters with excellent yields and enantioselectivities.
单硫丙二酸盐(MTMs)被引入作为硫酯烯醇等效物。对硝基烯烃的非对称有机催化的结合加成反应在温和条件下进行,获得合成有用的γ-硝基硫酸酯,产率和对映选择性均优异。
