• 10.3762/bjoc.14.206 Abstract The stereoselective total synthesis of strongylodiol H and I has been accomplished. The synthetic procedure comprised the stereoselective reduction of a ketone functionality in an ene–yne–one employing CBS as a catalyst and a Cadiot–Chodkiewicz coupling reaction as the key

• reaction steps. A common aldehyde intermediate has been used for the synthesis of both strongylodiols.
