Reaction of Functionalized Carbodiimide with α-Amino Ester: A Selective Synthesis of 2,3,5-Trisubstituted Imidazol-4-ones
摘要:
3-(Ethoxycarbonylmethylene)-2-(arylimino)-imidazol-4-ones 5 were synthesized selectively by reaction of -amino ester with carbodiimides 4, which were obtained from aza-Wittig reaction of iminophosphoranes 2 with aromatic isocyanates.
