cyanate gives 5-(5-hydroxy-3-indolylmethyl)hydantoin 5 or Nb-carbamoyl-5-hydroxy-L-tryptophan 6 depending on the reaction conditions. Reaction of 4 with methyl iso-cyanate in acetone provides 5-hydroxy-Nb-methylcarbamoyl-L-tryptophan 7. Treatment of 4 with ethyl, propyl and isopropyl isocyanates in acetone gives rise to the formation of the corresponding 2-[(3-alkyl-4,4-dimethyl-2-oxo)-1,3-diazetidinyl
