A generalmethod based on difference circular dichroic (DIF CD) spectroscopy for assigning the absoluteconfiguration of 1,2,4-triol is presented. Four possible stereoisomers of 6-heptene-1,2,4-triol were prepared and served as models to develop the procedure. The sign of the DIF CD Cotton effect is correlated to the absoluteconfiguration of the C2 position.

Abstract A simple and efficient stereoselective synthesis of 10-membered Benzannulated macrolactone, Sumalactone A has been accomplished from inexpensive and commercially available starting materials. This convergent synthesis utilizes Vilsmeier-Haack formylation, Jacobsen hydrolytic kinetic resolution, esterification under Yamaguchi conditions and ring-closing metathesis as key steps.
