Antimony(V) chloride-promoted room temperature aromatization of 1, 4-dihydropyridines in non-acidic solvent

Antimony(V) chloride acts as an efficient oxidant for the aromatization of 1, 4-dihydropyridines in dichloromethane at room temperature. The products of high purity were isolated after simple work-up in high-excellent yield. Plausible non-typical two- electron transfer mechanism of the reaction was postulated to explain results obtained with 4-alkyl substituted 1, 4-DHPs.
