Psilocin analogs. III. Synthesis of 5-methoxy- and 5-hydroxy-1,2,3,4-tetrahydro-9H-pyrido[3,4-b]indoles

AbstractA number of tetrahydro-β-carbolines were prepared with oxygen substituents at C-5. This class of compounds represents a hybrid between two naturally occurring groups of hallucinogenic molecules, the 4-hydroxytryptamines and the 6- and 7-oxygenated β-carbolines.
