Ring Closing Metathesis and Cross Metathesis of Carbohydrate

Derivatives.

-In connection with the synthesis of annonaceous acetoginins, the ring closing metathesis of the carbohydrate-derived unsaturated esters (I) to lactones (II) is detailed. Under similar conditions, cross metathesis between (III) and (IV) yields a single (E)-diastereomer. -(EL SUKKARI,
