Synthesis and Asymmetric Diels-Alder Reaction of Dimethyl ('d-Isoborneol-10-sulphinyl')maleate: Novel Route to Key Intermediates for Synthesis of Some Carbocyclic Nucleosides and Terpenoids

The chiral sulphoxide 1 was synthesized from 10-mercaptoisoborneol via diastereoselective oxidation.The dienophile 1 reacted with cyclopentadiene in the presence of a Lewis acid to give the adducts 7 and 8 with high diastereoselectivity (ca. 100percent).D
