M. Somei et al., SIMPLE SYNTHESES OF LESPEDAMINE AND 5-BROMO-N,N-DIMETHYLTRYPTAMINE BASED ON 1-HYDROXYINDOLE CHEMISTRY, Heterocycles, 40(1), 1995, pp. 119-122
Various types of 1-hydroxyindoles were prepared for the first time. Th
rough methylation or acid catalyzed nucleophilic bromination of N,N-di
methyl-1-hydroxytryptamine, simple syntheses of lespedamine and 5-brom
o-N,N-dimethyltryptamine were achieved, respectively.
