AbstractPsilocin 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.
