Various new C2-symmetric bidentate ligands, bearing phosphorus, nitrogen, and sulfur, were obtained in an efficient manner, starting from (±)-trans-3-methylidenecyclopropane-1,2-dicarboxylic acid (Feist's acid; (±)-trans-3). The structures of the new bidentate ligands, di(tert-butyl) (±)-[(trans-3-methylidenecyclopropane-1,2-diyl)dimethanediyl] biscarbamate ((±)-9), (±)-(trans-3-methyldienecyclopropane-1,2- diyl)dimethanaminium dichloride ((±)-10), (±)-S,S′-[(trans- 3-methylidenecyclopropane-1,2-diyl)dimethanediyl] diethanethioate ((±)-11), and (±)-[(trans-3-methylidenecyclopropane-1,2-diyl) dimethanediyl]bis(diphenylphosphane) ((±)-12), were fully characterized by standard spectroscopic techniques. These new classes of C2- symmetric bidentate ligands have the potential to be used in asymmetric catalysis. Copyright

(2R,3R)-(+)-Feist's acid has been converted via its dimethyl ester into (2R,3R)-(-bis(diphenylmethanol)-1-methylenecyclopropane, the corresponding bisdiol and bismesylate derivatives, and the racemic analogues of these derivatives has been converted into the bisazide, bis amino compounds and a bisindenyl derivative in good yields.
