(+)-Goniodiol 7 and (+)-9-deoxygoniopypyrone 8, belonging to the group of styryllactones, have been synthesized in five steps and 75% yield respectively from C4-esters 1a and 1b. The key step of these syntheses is a triflate-sulfone coupling which allowed a rapid construction of the backbone of the title compounds as well as the efficient installation of a masked Z-acrylate moiety.
