Access to combinatorial chemistry of hydantoins is provided by convenient and versatile methods for the solidphasesynthesis of libraries of 3,5-, 1,3- and 1,3,5-substituted hydantoins. The preparation of trisubstituted hydantoins features a Mitsunobu reaction for introduction of the substituent on N-1.

yl)-2-(O,S,Se)hydantoins were synthesized in the reaction of (adamantan-1-ylalkyl)heteroallenes with glycine ethyl ester hydrochloride under mild conditions in 75–85% yields. A method was developed for the synthesis of novel adamantan-1-ylalkyl isoselenocyanates, precursors in the synthesis of adamantylated 2-selenohydantoins. For the first time, 3-(adamantan-1-yl)-2-(O,S)hydantoins were synthesized
