Asymmetric palladium catalyzed allylic amination of 5 with various amines has been studied using a new class of chiral pyridine-phosphine ligands. High enantioselectivities of up to 94% ee have been observed using benzylamine, veratrylamine or morpholine as nucleophiles.
我们使用一类新型手性

膦配体,研究了
钯催化 5 与各种胺的不对称
烯丙基胺化反应。使用
苄胺、
藜芦胺或吗啉作为亲核剂,观察到高达 94%e 的高对映选择性。
