A palladium-catalyzed site-selective C-H carbonylation of heterocyclic amines for the synthesis of lactam motifs has been developed. The reaction of 3-thiophene methylamines, 2-thiophene methylamines, and tryptamines with benzene-1,3,5-triyl triformate (TFBen) as the CO source provides a series of structurally diverse lactams in moderate to high yields with excellent regioselectivities.
已经开发了钯催化的杂环胺的位点选择性CH羰基化反应,以合成内酰胺基序。3-噻吩甲胺,2-噻吩甲胺和色胺与苯-1,3,5-三甲酸酯三甲酸酯(TFBen)作为CO源的反应可提供一系列结构多样的内酰胺,中度至高产率,具有出色的区域选择性。
