A Sequential Metal-Catalyzed C−N Bond Formation in the Synthesis of 2-Amido-indoles
摘要:
A sequential metal-catalyzed C-N bond formation employing ortho-haloaryl acetylenic bromides is described. The initial amidation is highly selective for C-sp-N bond formation, leading to o-haloaryl-substituted ynamides that can be useful building blocks, while the overall sequence provides a facile construction of 2-amido-indoles.
