development of new practical and green methods for the synthesis of small heterocycles is an attractive area of research due to the well-known potential of heterocyclic small molecule scaffolds in the drug discovery process. Herein we report a one-pot, three-component sequential procedure for the synthesis of diversely 1,3,5- and 1,3,5,5-substituted hydantoins, in high yields and very mild conditions, using
Reaction of carbodiimides with α-Br(Cl)-aryl acetic acids produces N,N′-substituted 5-arylhydantoins under very mild conditions and high yields. When the carbodiimides are generated in situ by Staudinger reaction, the process becomes a one-pot, three-component sequential synthesis of libraries of differently substituted 5-arylhydantoins.
