Carbonylative N-Heterocyclization via Nitrogen-Directed C-C Bond Activation of Nonactivated Cyclopropanes

J Am Chem Soc. 2022 Jun 29;144(25):11069-11074. doi: 10.1021/jacs.2c02921. Epub 2022 Jun 17.

Abstract

Under Rh-catalyzed conditions, secondary amines and anilines function as directing groups to facilitate regioselective C-C bond activation of nonactivated cyclopropanes. The resulting amino-stabilized rhodacycles undergo carbonylative C-N bond formation en route to challenging seven- and eight-membered lactams. The processes represent rare examples where C-C bond oxidative addition of nonactivated cyclopropanes is exploited in reaction design.
