Total Synthesis of Gymnorrhizol, an Unprecedented 15-Membered Macrocyclic Polydisulfide from the Chinese Mangrove <i>Bruguiera gymnorrhiza</i>

Abstract

[reaction: see text] The total synthesis of gymnorrhizol, a naturally occurring macrocyclic polydisulfide with a new skeleton and a potent proteintyrosinephosphatase 1B inhibitor, was prepared in three steps, starting from (R)-1-bromo-3-chloroisopropanol and 1,3-dichloropropan-2-ol.
