experimental part, p. 629 - 636 (2012/08/29)
A series of (benzamidostyryl)benzimidazole derivatives were synthesized by hydrolyzing 2-phenyl-4-(substituted)benzylidene-5-oxazolones, the azlactone precursors in an acidic medium and treating the product with substituted o-phenylenediamine (OPDA) in si

A microwave-assisted solvent-dependent chemoselective reaction dealing with 4-arylidene-2-phenyloxazol-5-ones and diverse ortho-diamines to achieve three types of molecular scaffolds, 3-benzylquinoxalin-2(1H)-ones, benzimidazole and β-amino dipeptides is
Reaction of o-Phenylenediamine with 2-Oxazolin-5-ones
Tikdari, Ahmad M.,Mukerjee, Arya K.
, p. 73 - 74 (2007/10/02)
The reaction of o-phenylenediamine (2) with 2-oxazolin-5-ones (1a-c) gives benzimidazoles (4a-c) in the presence of gl. acetic acid.The intermediates 3a,b can be isolated only under neutral conditions. 4-(o-Aminoanilinomethylene)-2-phenyl-2-oxazolin-5-one (5) is formed, on heating 1d with 2, which is resistant to ring expansion.
BEHAVIOUR OF O-PHENYLENEDIAMINE AND O-AMINOTHIOPHENOL WITH AZIACTONES. A NEW SYNTHESIS OF SOME BENZIMIDAZOLE AND BENZOTHIAZOLE DERIVATIVES

, p. 1873 - 1881 (2007/10/02)
A new route for the preparation of benzimidazoles (5) and benzothiazoles (10) is described. o-Phenylenediamine reacted with 2-aryl-4-arylidene-2-oxazolin-5-ones to give the corresponding benzimidazole derivatives (5) while o-aminothiophenol produced eithe
