Abstract: A method for the synthesis of 2-amino-4-arylidene-1H-imidazol-5(4H)-ones is proposed based on the reaction of various aromatic isocyanates with phosphazenes derived from azidocinnamic acid amides. The spectral-luminescent properties of the obtained compounds were studied. The products… read more here.

Abstract: An efficient and practical method was developed for the synthesis of tetrahydro-1H-pyrrolo[1,2-a]imidazol-2-ones based on the decarboxylative cyclization reaction of α-ketoamides and proline. In most cases, tetrahydro-1H-pyrrolo[1,2-a]imidazol-2-ones were obtained with perfect diastereoselectivity to give trans-isomer in… read more here.
