Abstract
The first total synthesis of pinolide, a nonsymmetrical ten-membered macrocyclic, is described starting from readily available (–)-tartaric and L-ascorbic acid. The key synthetic steps include Barbier allylation, Yamaguchi esterification and ring-closing metathesis (RCM) reactions. The synthetic strategy has been successful for the construction of the ten-membered core skeleton. A facile and convergent approach enabled the incorporation of all the four stereogenic centers present in the molecule.
