Attempted synthesis of 2,3-dihydrofuro[2,3-b]indole from α-(o-nitrophenyl)-γ-butyrolactone was found to give 2-hydroxytryptophol in stead of the objective compound. 2-Hydroxytryptophol is a novel compound and several of its derivatives were synthesized ; 3-(1-ethyl-2-hydroxyethyl)oxindole (XV), 3-(2-ethyl-2-hydroxyethyl)oxindole (XVI), and 3-(2,2-dimethyl-2-hydroxyethyl)oxindole (XVII). Several novel α-phenyl-α-butyrolactone derivatives and their novel α-nitro- and aminophenyl derivatives were also synthesized ; α-(o-and p-nitrophenyl)-γ-butyrolactone (VI), α-(o-and p-nitrophenyl)-γ-ethyl-γ-butyrolactone (VIII), α-(p-aminophenyl)-α-ethyl-γ-butyrolactone (XI), α-(p-aminophenyl)-γ-ethyl-γ-butyrolactone (XII), and α-(p-aminophenyl)-γ, γ-dimethyl-γ-butyrolactone (XIII).
