Li, Bryan; Samp, Lacey; Sagal, John; Hayward, Cheryl M.; Yang, Christine; Zhang, Zhijun published the artcile< Synthesis of Quinazolin-4(3H)-ones via Amidine N-Arylation>, Recommanded Product: Methyl 2-bromo-5-fluorobenzoate, the main research area is trifluoromethyliodonicotinic acid amidine palladium catalyst arylation; pyridopyrimidinone preparation; amindine halobenzoate palladium catalyst arylation; quinazolinone preparation.

Pyrido[4,3-d]pyrimidin-4(3H)-one was prepared by reacting 2-trifluoromethyl-4-iodo-nicotinic acid with amidine I catalyzed by Pd2(dba)3 and Xantphos, followed by cyclization effected with HBTU and subsequent demethylation using PhBCl2. The amidine arylation method was found applicable for the syntheses of quinazolin-4(3H)-ones. Thus, reaction of 2-bromo or 2-iodo benzoate esters with amidines afforded substituted quinazolin-4(3H)-ones, e.g. II, in 44-89% yields.

Huang, Shuaishuai; Nie, Yixue; Yang, Jingjing; Zheng, Zhanjiang; Cao, Jian; Xu, Zheng; Xu, Liwen published the artcile< Copper-catalyzed arylated etherification of 2,2-difluoroethanol and its mechanistic study>, Electric Literature of 401-78-5, the main research area is haloarene difluoroethanol copper catalyst Ullmann type arylated etherification; difluoroethoxy arene preparation.

A mild and efficient method for the preparation of difluoroethyl aryl ethers was developed by the copper-catalyzed Ullmann-type arylated etherification reaction of aryl bromides or iodides with 2,2-difluoroethanol. This reaction proceeded smoothly in the presence of CuI and 8-hydroxyquinoline/t-BuOK and has a broad substrate scope. ESI-MS anal. supported the existence of LCu(III)Ar(OR) species during this catalytic reaction. Further d. functional theory (DFT) calculations suggested a proposed mechanism of arylated etherification reaction involving oxidative addition, followed by nucleophile substitution and reductive elimination would be rational.

The YAP-TEAD transcriptional complex is responsible for the expression of genes that regulate cancer cell growth and proliferation. Dysregulation of the Hippo pathway due to overexpression of TEAD has been reported in a wide range of cancers. Inhibition of TEAD represses the expression of associated genes, demonstrating the value of this transcription factor for the development of novel anti-cancer therapies. We report herein the design, synthesis and biol. evaluation of LM98, a flufenamic acid analog. LM98 shows strong affinity to TEAD, inhibits its autopalmitoylation and reduces the YAP-TEAD transcriptional activity. Binding of LM98 to TEAD was supported by 19F-NMR studies while co-crystallization experiments confirmed that LM98 is anchored within the palmitic acid pocket of TEAD. LM98 reduces the expression of CTGF and Cyr61, inhibits MDA-MB-231 breast cancer cell migration and arrests cell cycling in the S phase during cell division.

A silver-catalyzed hydroalkoxylation of C2-alkynyl quinazolinones to prepare a series of novel quinazolinone-fused eight-membered N,O-heterocycles I [X = O, N; R1 = H, 12-Me, 12-MeO, etc; R2 = H, 2-MeO, 2-Br, etc; R3=R4 = H, Me, etc; R5 = H, n-pentyl, Ph, etc] in good-to-excellent yields through a selective 8-endo-dig cyclization. Mechanistic studies revealed that the silver catalyst might aid bidentate coordination of an imine group and alkyne to facilitate 8-endo-dig cyclization to afford eight-membered N,O-heterocycles I. Also, the proposed bimetal silver intermediates might promote hydroalkoxylation rapidly for quinazolinones bearing terminal alkynes at the C2-position. Biol. evaluations revealed that most of the designed quinazolinone-fused eight-membered N,O-heterocycles I inhibited nitric-oxide generation significantly in lipopolysaccharide-stimulated RAW264.7 cells and displayed their bioactivity as potentially good anti-inflammatory agents.
