A novel general protocol for the construction of hydantoins and thiohydantoins on a solid support has been developed. Using this novel methodology, the synthesis of a diverse 96-compound library has been achieved. Resin-bound dipeptides are cyclised via the formation of an intermediate isocyanate or isothiocyanate on resin as the key step in the strategy.
