摘要:
Triple catalysis: The title reaction between α-branched aldehydes and allylic alcohols, which generates all-carbon quaternary stereogenic centers, constitutes the first asymmetric Tsuji-Trost-type α-allylation of carbonyl compounds with allylic alcohol (see scheme). This reaction is catalyzed by three different species, [Pd(PPh3)4], the chiral Brønsted acid TRIP, and benzhydryl amine. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
