Imidates derived from α-amino esters, undergo cycloaddition reactions as stabilized ylides, with imines in good yields.

The competing forces of a greater number of weak C-H?O interactions in the crystal structure of imidazolin-5-one analogues seem to tip the balance against the relatively stronger carbonyl-carbon (C=O δ-?Cδ+) electrostatic interaction previously observed and reported by us in the crystal structure of (4Z)-4-(4-methoxybenzylidene)-1,2-diphenyl-1,4-dihydro-5H-imidazolin-5-one [G. Bhattacharjya, G. Savitha, G. Ramanathan, Cryst. Eng. Commun. 6 (2004) 233].
Isothiocyanate-Mediated Condensation of N-Acyl-α-amino Acids with Aromatic Aldehydes: One-Pot Synthesis of 1,2-Disubstituted 4-Arylmethylene-2-imidazolin-5-ones

N-Acetyl/benzoyl-amino acids (1c/1b, d) when heated with isothiocyanates (2) in the presence of suitable aromatic aldehydes (3) with pyridine as a catalyst, afford 1, 2-disubstituted 4-arylmethylene-2-imidazolin-5-ones (6).However, N-benzyloxycarbonylaminoacetic acid (1a) gives the corresponding anilide (11a).Mechanisms of these reactions are discussed.
