A series of pyrrole- and indole-fused trifluoromethyl-functionalized piperazine derivatives were constructed in moderate to good yields with excellent chemoselectivities via a Pictet-Spengler reaction under mild and operationally simple conditions. The synthetic utility of this protocol was further extended by the facile preparation of indole-fused CF3-1,4-diazocane and enantioenriched CF3-piperazines via a vinylogous Pictet-Spengler reaction and an asymmetric Pictet-Spengler reaction, respectively.

2-Acyl-1-(phenylsulfonyl)indoles (3, 7-9) are prepared in 75-84% yield from 1-(phenylsulfonyl)indoles (1, 5) in one operation by treatment of the latter with s-butyllithium followed by inverse quenching of the C-2 lithioindoles with carboxylic acid anhydr
