摘要：
When treated with potassium t-butoxide and then with a palladium(O) complex, the title compounds 1, 2, or 9 are smoothly cyclized by an attack of the enolates onto the unsaturation assisted by a palladium (II) species of tBuO-Pd-H type. The formation of a five-membered ring is particularly favored in such a process.
