Di-l-menthyl (Acetoxymethylene)malonate, a New Chiral Dienophile: Enantioselective Route to Carbocyclic Analogues of C-Nucleoside

Titanium tetrachloride promoted Diels-Alder reaction of new chiral dienophile, di-l-menthyl (acetoxymethylene)malonate, with cyclopentadiene not only proceeds with high diastereofacial selectivity but also provides an efficient enantioselective synthetic
