title: Aerobic oxidative C-H olefination of cyclic N-sulfonyl ketimines catalyzed by a rhodium catalyst.
abstract: A useful method for the synthesis of ortho-olefinated ketimines from readily accessible cyclic N-sulfonyl ketimines and various olefins has been achieved. The reactions proceeded by Rh(III)-catalyzed, N-sulfonyl ketimine-directed C-H cleavage under aerobic conditions. Further synthetic transformations of the olefinic products led to interesting heterocyclic molecules.
