Pentaenolate activation in the organocatalytic allylic alkylation of indene-2-carbaldehydes

Chem Commun (Camb). 2023 Jun 15;59(49):7655-7658. doi: 10.1039/d3cc00900a.

Abstract

In this manuscript, the application of pentaenolate intermediates in the allylic alkylation of indene-2-carbaldehydes with Morita-Baylis-Hillman (MBH) carbonates is described. The reaction has been carried out in a highly enantio- and diastereoselective manner due to the use of a chiral tertiary amine as a nucleophilic catalyst. The developed reactivity constitutes the first application of organocatalytic pentaenolate activation in asymmetric synthesis, expanding the arsenal of catalytic methods.
