The title reactions proceeded smoothly and gave mixtures of four stereoisomeric cycloadducts differing in the configurations at C-8 and C-2, whose relative amounts varied depending on bulkiness of the 4-substituents and reaction temperature used.

A general efficient approach leading to the total synthsis of (±)-solavetivone, (±)-hinesol, and related spirovetivanes, is described. The process involves stereoselective formation of the asymmetric center at C-7 by π-cyclization as a key step.
