摘要:
Acyclic quaternary carbons by conjugate addition: The first examples of catalytic enantioselective conjugate additions of aryl and alkyl units that generate acyclic all-carbon quaternary stereogenic centers have been developed (see scheme). The requisite organoaluminum reagents can either be prepared in situ from easily available organolithiums or purchased at low cost. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
