Wang, Peng; Chen, Shuqing; Zhou, Zhiyu; Cheng, Hong-Gang; Zhou, Qianghui published the artcile< Chemoselective Borono-Catellani Arylation for Unsymmetrical Biaryls Synthesis>, Quality Control of 190788-60-4, the main research area is biaryl alkene alkenoate chemoselective diastereoselective preparation; palladium norbornenedicarboxylate catalyst borono Catellani reaction; chemoselective stereoselective arylation arylpinacolboronate bromoarene alkene palladium norbornenedicarboxylate catalyst.
In the presence of Pd(OAc)2 and a norbornenedicarboxylate, arylpinacolboronates such as 2-methylphenyl pinacolboronate underwent chemoselective aerobic borono-Catellani reactions with aryl bromides such as Me 2-bromobenzoate and alkenes (including α,β-unsaturated esters) such as tert-Bu acrylate to yield unsym. biaryl alkenes such as biphenylpropenoate I. In the absence of alkene, a bromophenylcarbamate underwent coupling and cyclization with 2-naphthylpinacolboronate to yield a mixture of benzocarbazoles in 45% combined yield; a bromophenol underwent coupling without cyclization.
