efficient method for the synthesis of 3-haloindoles has been developed. Both 3-chloro- and 3-bromoindole derivatives can be obtained in high yields by the reaction of N-electron-withdrawinggroup-substituted2-alkynylanilines with cupric halide in dimethyl sulfoxide (DMSO) within a short period of time. Investigation of the reaction mechanism reveals that two equivalents of cupric halide are necessary

In this study, we developed direct methods for the synthesis of 3-substituted indoles from o-allcynylan-ilines by utilizing a copper-catalyzed tandem intramolecular cyclization/coupling reaction under mild and simple reaction conditions. Our investigation revealed that choice of the aprotic polar solvents and additives such as camphorsulfonic acid is critical in this reaction. (C) 2013 Elsevier Ltd. All rights reserved.

Molecular design, synthesis, in vitro and in vivo studies of novel derivatives of indole-3-carboxylic acid new series of angiotensin II receptor 1 antagonists is presented. Radioligand binding studies using [125I]-angiotensin II displayed that newderivatives of indole-3-carboxylic acid have a high nanomolar affinity for the angiotensin II receptor (AT1 subtype) on a par with the known pharmaceuticals
