WebJan 6, 2024 · 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-allyl complex. WebOne-pot reaction of 2a required refluxing in dioxane to effect full conversion in the Tsuji–Trost reaction; however, the less sterically hindered aziridines 2b and 2c were found to react fully in THF. Importantly, scale-up of these reactions proved to be facile, with 6aa, 6ab, and 6bc being formed in equal or increased yield on a 3 mmol scale.
