The 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 readily accessible ...
