WebMar 31, 2024 · The Pd/PMe 3-catalyzed allylation of 1-(cyanomethyl)naphthalenes with allyl acetates proved to be para- rather than α-regioselective. This reaction is thought to proceed through ligand attack of the para-carbon in the arenes, electronically enriched by a cyano-stabilized α-carbanion, to the (π-allyl)palladium and a 1,5-hydrogen shift of the para … WebJun 21, 2024 · Asymmetric Pd-catalyzed Tsuji-Trost-type allylation is an important catalytic reaction toward chiral natural and unnatural product syntheses. We successfully modified a desalt-type reaction using allyl ester or halide to a dehydrative one using allylic alcohol via the establishment of two redox-mediated donor acceptor bifunctional catalyst systems. dynamic investments ltd
