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
取决于反应条件,具有氰酸钾的5-羟基-L-色氨酸4产生5-(5-羟基-3-吲哚基甲基)乙内酰脲5或N b-氨基甲酰基-5-羟基-L-色氨酸6。的反应4与甲基异氰酸盐在丙酮中提供5-羟基- ñ b甲基氨基甲酰基- L-色氨酸7。在丙酮中用乙基,丙基和异丙基异氰酸酯处理4会形成相应的2-[((3-烷基-4,4-二甲基-2-氧代)-1,3-二氮杂环丁烷基] -3-(5 -羟基-3-吲哚基)丙酸8-10。
