Catalytic C−H Amination for the Preparation of Substituted 1,2-Diamines

Abstract
Rhodium-catalyzed C−H insertion of hydroxylamine-derived sulfamate esters makes possible the synthesis of unique oxathiadiazinane heterocycles, which upon mild reduction furnish differentially substituted 1,2-diamine products. This highly chemo- and diastereoselective transformation underscores the power of catalytic C−H functionalization as a general approach to C−N bond construction.
