WebMay 14, 2024 · Generally, the enantioselectivity in the Tsuji-Trost reaction depends on both, steric and electronic properties of the η 3 palladium allylic complexes [9,10,11,12,13,14,15,16,17]. An attacking nucleophile favorably approaches the complexed allylic system from the site opposite to the more π-accepting ligand center.

The Tsuji–Trost reaction (also called the Trost allylic alkylation or allylic alkylation) is a palladium-catalysed substitution reaction involving a substrate that contains a leaving group in an allylic position. The palladium catalyst first coordinates with the allyl group and then undergoes oxidative addition, forming the π … See more In 1962, Smidt published work on the palladium-catalysed oxidation of alkenes to carbonyl groups. In this work, it was determined that the palladium catalyst activated the alkene for the nucleophilic attack of See more The enantioselective version of the Tsuji–Trost reaction is called the Trost asymmetric allylic alkylation (Trost AAA) or simply, asymmetric allylic alkylation (AAA). These … See more Pharmaceutical/natural products synthesis The ability to form carbon-carbon, carbon-nitrogen, and carbon … See more Starting with a zerovalent palladium species and a substrate containing a leaving group in the allylic position, the Tsuji–Trost reaction proceeds through the catalytic cycle outlined below.
