Acetone-sensitized photocycloaddition of ethylene to chiral butenolides 3 and 15 yields diastereomeric cyclobutanes, which are transformed to (+)-(1) and (-)-grandisol (ent-1) (overall yield 34-36percent) and to 2-ethanol (demethylgrandisol) (2) (overall yield 25percent) in five steps. Key Words: Photocycloaddition, / Grandisol, (+)- and (-)- / Grandisol, derivatives of
