In 2019,Chemistry – A European Journal included an article by Yuan, Shuo; Yu, Bin; Liu, Hong-Min. Electric Literature of C6H6BFO2. The article was titled 《””On-Water”” Palladium-Catalyzed Tandem Cyclization Reaction for the Synthesis of Biologically Relevant 4-Arylquinazolines》. The information in the text is summarized as follows:
The quinazoline scaffold is prevalent in pharmaceutically relevant mols. that show diverse biol. activities. An efficient “”on-water”” palladium-catalyzed tandem cyclization reaction from com. available arylboronic acids RB(OH)2 (R = Ph, 3-nitrophenyl, naphthalen-1-yl, etc.) and benzonitriles (E)-2-CN-R1C6H4N=C(R2)N(Me)2 [R1 = H, 5-Me, 4,5-(OMe)2, etc.; R2 = H, Me] that enable the rapid access to 4-arylquinazoline scaffolds I [R3 = H, 7-Me, 6,7-(OMe)2, etc.] in good to excellent yields (45 examples, up to 98% yield) was reported. This protocol has shown good functional group tolerance and broad substrate scope. The reaction was also performed on a gram scale and successfully applied to the synthesis of the highly potent and selective PI3Kδ inhibitor II, showing the practicability and synthetic utility of the protocol. In this reaction, the quinazoline scaffold I is efficiently constructed with the simultaneous formation of one C-C bond and one C-N bond. Collectively, the protocol could serve as an alternative strategy to synthesize biol. important quinazoline scaffolds. The experimental part of the paper was very detailed, including the reaction process of (3-Fluorophenyl)boronic acid(cas: 768-35-4Electric Literature of C6H6BFO2)
(3-Fluorophenyl)boronic acid(cas: 768-35-4) can be used to make novel liquid crystalline fluorobiphenylcyclohexenes and difluoroterphenyls by palladium-catalyzed cross-couplings also used in the synthesis of o-phenylphenols as potent leukotriene B4 receptor agonists.Electric Literature of C6H6BFO2
