A stereoselective one-pot transformation of simple enol-lactone
derivatives into the corresponding more complex compounds having the
bicyclo[m.n.1] ring system was investigated. Under
improved reduction conditions using DIBAL-H, the enol-lactones
efficiently provided the bicyclo[m.n.1] derivatives
via tandem reduction of the lactone moiety, aldol reaction and
subsequent reduction of the resulting carbonyl functionality.
