Olefin cross-metathesis/Suzuki–Miyaura reactions on vinylphenylboronic acid pinacol esters
摘要:
A series of alkenyl phenylboronic acid pinacol esters has been synthesized via an olefin cross-metathesis reaction of vinylphenylboronic acid pinacol ester derivatives. After catalytic hydrogenation, the resulting boronates were coupled via a microwave-mediated Suzuki-Miyaura reaction to afford a library of biarylethyl aryl and biarylethyl cycloalkyl derivatives. A complementary reaction sequence involved an initial Suzuki-Miyaura coupling. Crown Copyright (C) 2012 Published by Elsevier Ltd. All rights reserved.
