Reactions of tryptophols and Nα-acetyltryptamines with iodine azide. Formation of 3a-azido-3,3a,8,8a-tetrahydro-2H-furo- and 3a-azido-1,2,3,3a,8,8a-hexahydropyrrolo-[2,3-b]indoles

Abstract
Reaction of 2-methyltryptophol (1a) with 1 molar equivalent of iodine azide gives 3a-azido-8a-methyl-3,3a,8,8a-tetrahydro-2H-furo[2,3-b]indole, which isomerises to 2-azidomethyltryptophol in acetic acid at room temperature. Similar treatment of Nα-acetyl-2-methyltryptamine affords two products, 1-acetyl-3a-azido-8a-methyl-1,2,3,3a,8,8a-hexahydropyrrolo[2,3-b]indole and Nα-acetyl-2-azidomethyltryptamine; the former does not isomerise to the latter in acetic acid. Tryptophol and Nα-acetyltryptamine also give the corresponding 3a-azidofuro and -pyrrolo-indole derivatives in low yields.
