  We disclose the first catalytic domino reaction of α-(2-formylaryloxy)acetonitriles with arylboronic acids, yielding a range of 2-aroylbenzo[b]furans with yields of up to 93%. Ni(acac)2 serves as an effective dual catalyst. The protocol is also applicable to α-(2-acetylphenoxy)acetonitrile, giving rise to 3-methyl-2-aroylbenzo[b]furans. This domino process is efficient, additive-free, and compatible

  The synthesis of a series of novel 1-[(benzofuran-2-yl)phenylmethyl]-pyridine, -imidazole, and -triazole derivatives is described. All the compounds were evaluated in vitro for inhibitory activity against aromatase (P450(AROM), CYP19), using human placental microsomes. The 6-methoxy- and 6-hydroxy-substituted benzofuran derivatives were shown to be potent CYP19 inhibitors (IC50 = 0.01-1.46 mu M) with activity greater than that observed for the unsubstituted parent compounds and inhibitory activity comparable with or greater than the reference compound arimidex (IC50 = 0.6 mu M). Six of the benzofuran derivatives were subjected to in vitro cytotoxicity assays, using rat liver hepatocytes with cytotoxicity determined from alteration in cell morphology and lactate dehydrogenase enzyme retention over a period of 24 h, and selectivity (CYP17, 17 beta-HSD types 1 and 3, CYP24, and CYP26) determination; negligible inhibitory activity was observed, suggesting a good selectivity for CYP19. The pyridine benzofuran 4a containing the 4-fluorophenyl group was the most promising (IC50 = 44 nM; LC50 > 100 mu M) compared with arimidex (IC50 = 600 nM; LC50 > 200 mu M).
