A palladium-catalyzed cross-coupling reaction of azides with isocyanides is developed, providing a general synthetic route to unsymmetric carbodiimides.
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
An efficient and mild oxidative desulfurization procedure using o-iodoxybenzoic acid has been developed for the synthesis of carbodiimides starting from easily synthesizable 1,3-disubstituted thioureas.
