Not salen, but salan: A new dinucleating salan‐type ligand 1 was developed for the enantioselective decarboxylative 1,4‐addition of malonicacid half‐thioester to nitroalkenes. A Ni/La/1 complex gave products in 99–40 % yield and 94–66 % ee.
不是salen,而是salan:开发了一种新的双核salan型配体1,用于丙二酸半硫酯对硝基烯烃的对映选择性脱羧1,4加成。Ni / La / 1复合物的产率为99–40%,ee为94–66%。
