catalyzed enantioselective conjugate addition of diethylzinc to nitroalkenes, using up to nine different nitroalkenes in a one pot procedure. The 18 products (9 times 2 enantiomers of nine different nitroalkanes) can be analyzed by chiral CG in a single run since on overlap in the peaks is observed. The obtained enantioselectivities are amongst the highest reported so far for the catalytic 1,4-addition
多底物方法用于在一锅法中最多使用九种不同的硝基烯烃,将铜-亚铁酰胺催化的二乙基锌与硝基烯烃的对映选择性共轭加成反应。可以通过手性CG在一次运行中分析18种产物(9种不同硝基链烷烃的9对2对映体),因为观察到峰重叠。获得的对映选择性是迄今为止报道的将二烷基锌试剂催化1,4-加成到硝基烯烃中的最高对映选择性。
