## Abstract Reaction of tryptamine (1) with 2 and 3 gives the enamino ketones 4a and 5, resp., which on treatment with trifluoroacetic acid lead to the 2‐substituted indoles 8 and 9, respectively. Acylation of 4a followed by reaction with trifluoroacetic acid or a Lewis acid affords the 1,2,3,4‐tet
