Regioselective synthesis of pyridines by redox alkylation of pyridine N-oxides with malonates.


ABSTRACT:

Abstract

A regioselective synthesis of pyridines by the addition of malonate anions to pyridine N-oxide derivatives, which have been activated by trifluoromethanesulfonic anhydride, is reported. The reaction selectively affords either 2- or 4-substituted pyridines in good yields.
