  • Title: Chemoselectivity of the Ru-catalyzed cycloisomerization reaction for the synthesis of dihydropyrans; application to the synthesis of L-forosamine.
    Author: Zacuto MJ, Tomita D, Pirzada Z, Xu F.
    Journal: Org Lett; 2010 Feb 19; 12(4):684-7. PubMed ID: 20088537.
    Abstract:
    The chemoselectivity of a Ru-catalyzed cycloisomerization reaction has been established. The preference for O- capture of the vinylidene intermediate allows for the synthesis of 4-aminodihydropyrans that are valuable synthetic intermediates. The synthetic utility of these structures has been demonstrated in the synthesis of l-forosamine.
