[Structure: see text] Homoallylic amines and alpha-amino esters were prepared via a Pd(II)-catalyzed coupling of boronic acids and 1,2-nonadiene with ethyl iminoacetate or aliphatic, aromatic, and heteroaromatic imines. The allylpalladium umpolung was induced by a Pd(OAc)2 catalyst with commercial phosphine ligands.
[结构:见正文]均烯丙基胺和α-氨基酯是通过硼酸和1,2-壬二烯与亚氨基乙酸乙酯或脂族,芳族和杂芳族亚胺经Pd(II)催化偶联制得的。烯丙基钯化合物是由具有商业化膦配体的Pd(OAc)2催化剂诱导的。
