An alternative procedure for the synthesis of 2,5-disubstituted-3,5- dihydro-imidazol-4-ones from substituted oxazolones was evaluated. The initial oxazolone ring-opening reaction was examined with a variety of ammonia source compounds followed by the sub

Twenty five unsaturated 2,4-disubstituted 2-imidazolin-5-ones (IV) have been prepared in 23-71percent yields by condensing aromatic aldehydes with a mixture of ethyl chloroacetate and an aromatic amidinium chloride in the presence of sodium hydrogencarbonate.Twenty three of them have also been prepared in 62-97percent yields by this method using ethyl bromoacetate instaed of the chloroacetate.Further, two unsaturated 2-imidazolin-5-ones (IV) have been prepared by these two methods using cyclohexanone (yields 33percent each) and cinnamaldehyde (yields 0 and 18percent) instead of the aromatic aldehydes.
