✦ Synopsis

afforded in the completely stereoselective synthesis of (S)-massiolactone the enantiomer of the natural product in 90.516 optical purity. Assuming the reactant (S)-fSb) to have the same optical purity, then a = -15.5" can be calculated for optically pure (S)-l.2-epoxyheptane (S)-(5b); a value of a?, = -15 6" ( c = 1.816, ethanol) was measured.
