Abstract:
Aromatic aldehydes and hippuric acid in acetic anhydride undergoes classical Erlenmeyer synthesis in the presence of a catalytic amount of Montmorillonite K-10 to afford the corresponding azlactones in excellent yields with high selectivity. The azlactone formation does not proceed in the absence of either acetic anhydride or Montmorillonite.

Abstract:
Introduction: Cancer is still an untreatable disease and the second leading cause of death globally. The heterocyclic compounds have always played a major role in the anticancer drug discovery program. 1,2,4-Triazine-6-ones is a heterocyclic privileged structure with diversified activities. In the presented study, 21 novel 2,5-disubstituted-3-phenyl-1,2-dihydro-1,2,4-triazin-6 (5H)-one derivatives (13(a-k), 18(a-j) and 21(a1-a4, b)) have been synthesized and tested for their anticancer activity. Methods: The 2,5-disubstituted-3-phenyl-1,2-dihydro-1,2,4-triazin-6(5H)-one derivatives (13(a-k), 1

Abstract:
The zwitterionic imidazolium salt was prepared and characterized by1H NMR. It was first used for synthesis of azlactones via Erlenmeyer synthesis from aromatic aldehydes and hippuric acid under solvent-free conditions. It was found that aldehyde substituents play an important role in these reactions. Better conversions and therefore higher isolated yields were observed when electron-withdrawing groups (EWG-) were present in the aromatic aldehyde. Opposite results were shown when electron-donating groups (EDG-) were present in the aromatic aldehyde. However, azlactones were obtained in moderate

Revised mechanism and improved methodology for the perkin condensation.1 The generally accepted mechanism for the well-known Perkin condensation is unviable for at least two reasons: (1) the normally employed base, acetate ion, is too weak to deprotonate acetic anhydride (Ac2O, the substrate); and (2) even were Ac2O to be derprotonated , its anion would rapidly fragment to ketene and acetate ion at the high temperatures employed for the reaction.
