C-N coupling of indoles and carbazoles with aromatic chlorides catalyzed by a single-component NHC-nickel(0) precursor

A new and efficient nickel-based protocol for the N-arylation of indoles and carbazoles with aromatic chlorides, the least expensive of the aryl halides, is described. The procedure provides selectively N-(hetero)arylation products in good to high yields, in short reaction times and without adding an excess of ligands.

Synthesis and antidiabetic activity of 3,6,7-trisubstituted-2-(1H-imidazol- 2-ylsulfanyl)quinoxalines and quinoxalin-2-yl isothioureas

Two series of 3,6,7-trisubstituted-2-(1H-imidazol-2-ylsulfanyl)- quinoxalines 2a-1 and 2-(quinoxalin-2-yl)-isothioureas 3a-1 were prepared. All the test compounds 2a-1 and 3a-1 were screened in vitro, in a RIN5F cell-based assay for glucose-dependent insulinotropic activity. A significant concentration and glucose-dependent insulin secretion effect was seen with compounds 2a-1 and the insulinotropic activity of compound 21 was found to be identical to that of the standard compound (6,7-dichloro-2-trifluromethyl-3-(5-methyl-1,3,4- thiadiazo-2-ylsulfanyl)-quinoxaline (1)).
