Various types of 1-hydroxyindoles were prepared for the first time.Through methylation or acid catalyzed nucleophilic bromination of N,N-dimethyl-1 -hydroxytryptamine, simple syntheses of lespedamine and 5-bromo-N,N-dimethyltryptamine were achieved, respectively.~espedaminez (1 a, Scheme 1) was isolated from Lespedeza bicolorvar.japonica Nakai and -b r o m o -~, ~-d i m e t h ~l t r y ~t a m i...
