A new synthesis of indoles via intramolecular cyclization of ο-alkynyl N,N-dialkylanilines promoted by KOt-Bu/DMSO
摘要:
2-Aryl indoles could be prepared in excellent yields via the intramolecular cyclization of o-alkynyl N,N-dialkylanilines. The reaction is efficiently promoted by the catalytic amount of KOr-Bu in DMSO at room temperature. A reaction mechanism involving alpha-aminoalkyl radical intermediates is suggested.

annulative couplings of 2-alkenylanilines with aldehydes using alcohols as both the solvent and hydrogen source have been developed. These domino processes allow divergent syntheses of two significant N-heterocycles, indoles and quinolines, from the same substrate by tuning reaction parameters, which seems to invoke two distinct mechanisms. The nature of the ligand and alcoholic solvent had a profound

small molecule drug-like inhibitors blocking both nitricoxide synthase and NFκB could offer a synergistic therapeutic approach in the prevention and treatment of inflammation and cancer. During the course of evaluating the biological potential of a commercial compound library, 2-phenylindole (1) displayed inhibitory activity against nitrite production and NFκB with IC50 values of 38.1 ± 1.8 and 25.4
