1-Hydroxyindoles produced novel types of compounds such as 4-substituted indoles and 4H-1,3-dioxolo[4,5-b]indoles upon reaction with p-toluenesulfonyl chloride in acetone. Contrastively, 5-tosyloxyindole and 2H-1,2-oxazino[2,3-a]indole were generated upon reaction with p-toluenesulfonic acid in acetone.
Novel formations of 6-mesyloxytryptamines and 1-substituted 3a-(4- chlorobutoxy)-1,2,3,3a,8,8a-hexahydropyrrolo[2,3-b]indoles in the reaction of nb-substituted 1-hydroxytryptamines with mesyl chloride

Formations of 6-mesyloxytryptamines and 1-substituted 3a-(4- chlorobutoxy)-1,2,3,3a,8,8a-hexahydropyrrolo[2,3-b]indoles were newly found in the reactions of Nb-substituted 1-hydroxytryptamines with mesyl chloride in THF. The latter compounds suggest that

A novel methodology for introducing chlorine or bromine into the 5- position of tryptamines was found through 1-hydroxytryptamines. The chemistry was applied to the syntheses of (±)-5-chloro-, -5-bromotryptophan derivatives, and (±)-bromochelonin B.
