Enantioselective Synthesis of the Functionalized Bicycloheptane Derivatives, Key Intermediates for the Chiral Synrhesis of Santalenes and Santalols

Article abstract of DOI:10.1246/cl.1986.1225

Optically active functionalized bicyclo<2.2.1>heptane derivatives obtained by the asymmetric Diels-Alder cycloaddition of ethyl p-tolylsulfinylmethylenepropionate with cyclopentadiene provide the potentially useful intermediates for synthesis of bicyclic sesquiterpenes such as (+)-epi-β-stanalene.
