  Synthesis of homochiral pyridyl, bipyridyl and phosphino derivatives of 2,2-dimethyl-1,3-dioxolane: Use in asymmetric catalysis

  摘要：

  Homochiral pyridyl, bipyridyl and phosphino derivatives of 2,2-dimethyl-1,3-dioxolane were prepared from L-(+)-tartrate. These compounds were assessed in metal catalyzed asymmetric addition of diethylzinc to benzaldehyde, hydroformylation of styrene, hydrocarboethoxylation of styrene and allylic alkylation of 1,3-diphenyl-2-propenyl acetate with dimethyl malonate.

  structure of compound 1 has been solved by X-ray diffraction: the ligand is co-ordinated through both the P and N atoms to form a seven-membered ring which adopts a chair conformation. One of the hydrogen atoms of the backbone is located 2.72(3)Å over the palladium atom in a pseudo-axial position. Spectroscopic evidence supports a chelating behaviour of the ligand also in compounds 2 and 3. The behaviour of
