The first catalytic asymmetric synthesis of axially chiral anilides has been carried out under palladium-catalyzed allylation reaction conditions with chiral phosphine ligands. Allylation of anilides bearing an orthotert-butyl group with a palladium catalyst and (S)-BINAP as a chiral ligand gave axially chiral anilides in about 50% ee.
在具有手性膦配体的钯催化的烯丙基化反应条件下已经进行了轴向手性苯甲酸酯的第一催化不对称合成。用钯催化剂和(S)-BINAP作为手性配体对带有邻叔丁基的苯甲酸酯进行烯丙基化,得到轴向手性苯甲酸酯为约50%ee。
