A general procedure for the reductive coupling of N-tosylhydrazones with amines in the presence of Cu(acac)2 and Cs2CO3 has been developed. The protocol is very effective and chemoselective with various primary and secondary aliphatic amines, aminoalcohols as well as azole derivatives to give α-branched amines in good yields.
已经开发出一种通用程序,在Cu(acac)2和Cs2CO3的存在下,将N-甲苯磺酰腙与各种伯胺、仲胺、氨基醇以及氮杂环衍生物还原耦合,以良好收率得到α-支链胺。该方法非常有效且化学选择性好。
