ω-[(4Z)-2-Aryl-4-arylmethylidene-5-oxo-4,5-dihydro-1H-imidazol-1-yl]alkanoic acids were synthesized by reaction of N-substituted α,β-dehydropeptides with chloro(trimethyl)silane or 1,1,1,3,3,3-hexamethyldisilazane. Both initial peptides and (4H)-imidazol-

The efficient synthesis of 4-arylidene-2-phenyl-1H-imidazol-5(4H)-ones was achieved via microwaveassisted reactions of 4-arylmethylene-2-phenyloxazol-5(4H) -ones with urea in glycol. This approach provides a facile shortcut for the synthesis of this type
