  • Title: Synthesis of the C1-C17 segment of phorboxazole B.
    Author: Lucas BS, Luther LM, Burke SD.
    Journal: Org Lett; 2004 Aug 19; 6(17):2965-8. PubMed ID: 15330659.
    Abstract:
    The C1-C17 bis-oxane subunit 22 of phorboxazole B is efficiently synthesized by exploiting differential reactivities between similar substituents on the hydropyran rings in 4. Selective dihydroxylation of the equatorial vinyl group, hydroboration of the axial vinyl group, and intramolecular Mitsunobu lactonization serve to fully differentiate the similar hydropyrans.
