  • Title: Two-step one-pot synthesis of benzoannulated spiroacetals by Suzuki-Miyaura coupling/acid-catalyzed spiroacetalization.
    Author: Butkevich AN, Corbu A, Meerpoel L, Stansfield I, Angibaud P, Bonnet P, Cossy J.
    Journal: Org Lett; 2012 Oct 05; 14(19):4998-5001. PubMed ID: 22998767.
    Abstract:
    Substituted benzoannulated spiroacetals were prepared from (2-haloaryl)alkyl alcohols and dihydropyranyl or dihydrofuranyl pinacol boronates using a Suzuki-Miyaura coupling followed by an acid-catalyzed spirocyclization. Application of the reaction to a glycal boronate provides an approach to annulated spiroacetals in enantiopure form.
