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
3-Arylidene derivatives of 3H-furan-2-ones. Synthesis and reaction with maleic anhydride
The synthesis of 5-alkyl(aryl)-3-arylidene-3H-furan-2-ones was accomplished, and their reaction with maleic anhydride was studied. The configuration, of the initial arylidene derivatives was established on the basis of the PMR spectra of the adducts obtai
