Abstract
Psilocin analogs having either a formyl group (9-12) or a bromine atom (13-18) at the 5-or 7-position have been prepared for the first time. Syntheses of 5-and 7-bromo derivatives of 4-hydroxy- (23-24,28) and 4-benzyloxyindole-3-carbaldehyde (19,25,29-30), 4-benzyloxyindole-3-acetonitriles (20,31), and 4-benzyloxy-N,N-dimethyltryptamine (32,34-35) have also been established.

This is really cool. 7-Formyl indoles are not easily accessable.
