  • Title: A diastereoselective one-pot, three-step cascade toward α-substituted allylboronic esters.
    Author: Böse D, Niesobski P, Lübcke M, Pietruszka J.
    Journal: J Org Chem; 2014 May 16; 79(10):4699-703. PubMed ID: 24745807.
    Abstract:
    A new highly diastereoselective synthesis of chiral α-substituted allylboronic esters, based on a one-pot, three-step cascade, is presented. The palladium- and acid-cocatalyzed reaction cascade involves a desilylation of a TBS-protected allylic alcohol, borylation, and addition of an allyl group to an aldehyde. Herein we present the first application of a TBS-protected allylic alcohol in a palladium-catalyzed borylation/allylation reaction.
