2-alkenoyl pyridine N-oxides, highly efficient dienophiles for the enantioselective Cu(II)-bis(oxazoline) catalyzed Diels-Alder reaction.

Santiago Barroso1, Gonzalo Blay, José R Pedro.   

Abstract

2-Alkenoyl pyridine N-oxides are introduced as a new kind of efficient dienophiles for the Cu(II)-bis(oxazoline) (BOX) catalyzed enantioselective Diels-Alder reaction affording higher reactivity and enantioselectivity (ee's up to 96%) than the corresponding nonoxidized 2-alkenoyl pyridines.
