Oxaziridine-mediated intramolecular amination of sp(3)-hybridized C-H bonds.


ABSTRACT: We describe a new oxaziridine-mediated approach to the amination of sp(3)-hybridized C-H bonds. In the presence of a copper(II) catalyst, N-sulfonyl oxaziridines participate in efficient intramolecular cyclization reactions to afford a variety of piperidine and tetrahydroisoquinoline structures. The aminal intermediates provide a convenient functional handle for further elaboration of these structures, demonstrating the utility of this new methodology for the rapid construction of structurally complex nitrogen-containing heterocycles.
