Abstract

(1'R)-(+)-3-Hydroxymethyl-1-(1'-phenyl-ethyl)-pyridinium chloride (1), 1-benzyl-3-[1', 3']-dioxolan-2'-yl-pyridinium chloride (2) and (2'S, 4'S, 5'R)-(-)-1-benzyl-3-(3',4'-dimethyl-5'-phenyl-oxazolidin-2'-yl)-pyridinium bromide (3), were transformed by oxidation with potassium ferricyanide into the corresponding 1H-pyridin-2-ones in excellent yields with high regioselectivity.
Keywords: pyridinium salts; regioselective oxidation and chirality pyridinium salts; regioselective oxidation and chirality
