Synthesis of 1-substituted tetrahydrocarbazole is accomplished by TfOH catalyzed reaction of 3-substituted indoles tethered with secondary and tertiary alcohols. The reaction was generalized for a variety of substrates and was extended to the synthesis of 2,3,3a,6-tetrahydro-1H-pyrido[3,2,1-jk]carbazole and carbazoles.
1-取代的四氢咔唑的合成是通过TfOH催化的与仲和叔醇连接的3-取代的吲哚的反应来完成的。该反应被推广用于多种底物,并扩展到2,3,3a,6-四氢-1 H-吡啶并[3,2,1- jk ]咔唑和咔唑的合成。

A series of 2(1H)-pyrrolidino [3,2-g]quinolinones was prepared and tested for the ability to modulate the transcriptional activity of the human androgen receptor (hAR). The parent compound, 4-(trifluoromethyl)-2(1H)-pyrrolidino[3,2-g]quinolinone, displayed moderate interaction with hAR, but more substituted analogues, particularly 6,7-disubstituted compounds, were potent hAR agonists in vitro.
