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.
