Metal hydride reductions of endo-tricyclo[5,2,1,02,6]deca-4,8-dien-3-one (endo-dicyclopentadienone)
Abstract
Aluminium hydride, lithium tri-t-butoxy-aluminium hydride, and sodium borohydride reduce specifically the carbonyl group, the double bond, and both the carbonyl group and the double bond, respectively, of a conjugated cyclopentenone, while lithium aluminium hydride gives all three products in varying amounts depending on the reaction conditions.
