Palladium-catalyzed Tsuji-Trost-type reaction of benzofuran-2-ylmethyl acetates with nucleophiles. RSC Adv 2020; 11:909-917.

Abstract
The palladium-catalyzed benzylic-like nucleophilic substitution of benzofuran-2-ylmethyl acetate with N, S, O and C soft nucleophiles has been investigated. The success of the reaction is dramatically influenced by the choice of catalytic system: with nitrogen based nucleophiles the reaction works well with Pd2(dba)3/dppf, while with sulfur, oxygen and carbo-nucleophiles [Pd(η3-C3H5)Cl]2/XPhos is more efficient. The regiochemical outcome shows that the nucleophilic substitution occurs only on the benzylic position of the η3-(benzofuryl)methyl complex. The high to excellent yields and the simplicity of the experimental procedure make this protocol a versatile synthetic tool for the preparation of 2-substituted benzo[b]furans.

Abstract
Novel 1H-purin-6(9H)-one (D) and 3H-imidazo[4,5-d][1,2,3]trazin-4(7H)-one (E) derivatives were designed, synthesized, and characterized by 1H NMR, 13C NMR and high-resolution mass spectrometry spectra. Their herbicidal activity bioassay showed that compound 7d exhibited relatively good activity with 70.4% inhibition rate against Amaranthus retroflexus in postemergence treatments at 1500 g/ha. Antitumor activity indicated that most of the title compounds displayed potent antitumor activity at 20 μM, among all of the promising compounds possessing lower IC50 values than that of temozolomide, compound 7i demonstrated highest activity inhibiting both HepG-2 and U-118 MG cell lines with IC50 values of 2.0 and 3.8 μM, respectively. The structure-activity relationship analysis revealed that introduction of halogen atoms, a bulky bridging bond between benzene ring and nitrogen atom, longer R2 substituents could contribute to the improvement of antitumor activity. Analysis suggested that compound 7i might have potential as new highly active antitumor agent. Overall, D series had better anticancer activities than E series derivatives.

Abstract
A series of 2-arylbenzo[b]furan–appended 4-aminoquinazoline hybrids were prepared and evaluated for cytotoxicity in vitro against the human lung cancer (A549), colorectal adenocarcinoma (Caco-2), hepatocellular carcinoma (C3A) and cervical cancer (HeLa) cell lines. Compounds 10d and 10j exhibited significant cytotoxicity against the C3A and Caco-2 cell lines and induced apoptosis in these cell lines. Likewise, compounds 10d and 10e exhibited significant inhibitory activity towards epidermal growth factor receptor-tyrosine kinase phosphorylation (IC50 values of 29.3 nM and 31.1 nM, respectively) against Gefitinib (IC50 = 33.1 nM). Molecular docking of compounds 10 into EGFR-TK active site suggests that they bind to the region of EGFR like Gefitinib does.

Abstract
A series of 2-arylbenzo[c]furan-chalcone hybrids 3a⁻y have been synthesized and evaluated for antiproliferative effects against the human breast cancer (MCF-7) cell line and for its potential to induce apoptosis and also to inhibit tubulin polymerization and/or epidermal growth factor receptor-tyrosine kinase (EGFR-TK) phosphorylation. Most of these compounds exhibited moderate to significant antigrowth effects in vitro against the MCF-7 cell line when compared to the reference standard actinomycin D. The capabilities of the most cytotoxic benzofuran-chalcone hybrids 3b and 3i, to induce apoptosis, have been evaluated by Annexin V-Cy3 SYTOX staining and caspase-3 activation. The experimental and molecular docking results suggest that the title compounds have the potential to exhibit inhibitory effects against tubulin polymerization and epidermal growth factor receptor tyrosine kinase (EGFR-TK) phosphorylation. The modeled structures of representative compounds displayed hydrophobic interactions as well as hydrogen and/or halogen bonding with the protein residues. These interactions are probably responsible for the observed increased binding affinity for the two receptors and their significant antigrowth effect against the MCF-7 cell line.

Abstract
The scope and the generality of gold versus silver catalyzed intramolecular hydroarylation reactions of 3-[(3-arylprop-2-ynyl)oxy]benzene derivatives in terms of rings substitution were investigated. Only products deriving from 6-endo cyclization were exclusively formed. The features of substituents had a considerable effect on the reaction outcome in the presence of silver catalysis, whereas gold catalysis revealed a unique blend of reactivity and selectivity and represented the only choice for the intramolecular hydroarylation reaction of the starting substrates bearing electron deficient arenes.
