Titanium Tetrachloride-Mediated Diels-Alder Reactions of Cyclopentadiene with Di-l-menthyl Methylenemalonate and Its Acetoxy Derivative as New Chiral Dienophiles for Asymmetric Induction

Asymmetric synthesis of -2,3-dihydroxy-4-hydroxymethylcyclopent-1ylmalonate (its racemic form is already known as a versatile building block for carbocyclic C-nucleosides) was achieved by Diels-Alder reaction of cyclopentadiene with di-l-ment

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
