Reaction of functionalized carbodiimide with α-amino ester: A selective synthesis of 2,3,5-trisubstituted imidazol-4-ones
3-(Ethoxycarbonylmethylene)-2-(arylimino)-imidazol-4-ones 5 were synthesized selectively by reaction of α-amino ester with carbodiimides 4, which were obtained from aza-Wittig reaction of iminophosphoranes 2 with aromatic isocyanates. Copyright Taylor & F
