One-pot synthesis of E-alkylidene derivatives of 3H-furan-2-ones from 4-pentynoic acid and aldehyde

4-Pentynoic acid reacts with aldehyde under the co-catalyst system of Wilkinson's complex and 2-aminopyridine to give E-alkylidene derivatives of 3H-furan-2-one through the transition metal-catalyzed cyclization of 4-pentynoic acid followed by condensatio
