Exploring new uses for C-H amination: Ni-catalyzed cross-coupling of cyclic sulfamates

Abstract

[reaction: see text] Benzene-fused cyclic sulfamates are prepared from ortho-substituted phenolic starting materials through selective C-H amination or olefin aziridination. These unique heterocycles will engage in Ni-catalyzed cross-coupling reactions with aryl- and alkyl-Grignard reagents. Application of modern tools for C-N and C-C bond formation thus makes readily available functional amine derivatives and augments the possible uses for C-H amination in synthesis.
