  New chiral ligands based on (+)-α-pinene

  摘要：

  A number of new chiral ligands were synthesized starting from an accessible monoterpene, (+)-alpha-pinene. The new ligands were used in the vanadium-catalyzed oxidation of sulfides to chiral sufoxides.

  α-Pinene-type chiral Schiff bases as tridentate ligands in asymmetric addition reactions

  摘要：

  A group of tridentate Schiff bases derived from (+)-alpha-pinene were synthesized. The steric effects in the transition state, the importance of pi-pi stacking interactions as well as the electronic effects of aryl aldehydes according to Hammett constant values in the enantioselective addition of Et2Zn to aldehydes with the use of Schiff bases as chiral ligands are described. Also, a variety of aldehydes were cyanated using a catalyst prepared in situ from titanium tetraisopropoxide and chiral Schiff bases. The influence of a conjugated double-bond in the cyanation substrates on enantioselectivity was observed. The chemical structures of the chiral Schiff base-titanium alkoxide complexes are discussed based on their H-1 and C-13 NMR spectra. 3D models of the Zn-2-complex catalyst and Ti-complex catalyst containing alpha-pinane-type Schiff bases based on X-ray diffraction experiments are postulated. The models presented were consistent with the reported chirality of the addition product and observed ee. (C) 2011 Elsevier Ltd. All rights reserved.
