Abstract
Résumé/Abstract 4-Alkylation of pyridine has been accomplished by the reaction of ylides, derivated from 1, 4-dihydropyridine phosphonate via phosphonioalkoxy-carbonylation of pyridine with aldehydes and subsequent elimination of diisopropyl phosphate followed by aromatization with potassium tert-butoxide.
