摘要：
Mild palladium-catalyzed spirocyclizations of 1-(3-hydroxyalkyl)- and 1-(4-hydroxyalkyl)-1,3-cycloalkadienes (5a, 5b, 5d, and 5e) have been developed. The reactions proceed via a spirocyclic pi-(allyl)palladium intermediate and result in the 1,4-addition of the hydroxy function and a chloride or an acetate. The stereochemistry of the reactions can be controlled to give either cis or trans 1,4-addition across the double bond.
