four sets of camphorimine complexes based on the Cu(I), Cu(II), Ag(I), and Au(I) metal sites were assessed against the cisplatin-sensitive A2780 and OVCAR3 ovarian cancer cells. The results showed that the goldcomplexes were ca. one order of magnitude more active than the silvercomplexes, which in turn were ca. one order of magnitude more active than the coppercomplexes. An important finding was

Seven new camphor palladium or platinum compounds with novel metal coordination environments were obtained by convenient choice of the experimental conditions in particular the solvent. cis-[PtCl2(PhNC10 H14O)(2)]) and [Pd(MeNNC10H14O)(2)] were structurally characterized by X-ray diffraction analysis while [PtCl2(Me2NC10H13NSO2)}(2)], [PdCl2(YNC10H14O)}(2)] (Y = NMe2, NPh2) and [Pd(PhNNC10H14O)(2)] were formulated by elemental analysis and spectroscopic techniques. Relevant aspects of the IR and NMR spectra of complexes [Pd(YNC10H14O)(2)] (Y = MeN, PhN) are discussed with the help of DFT calculations. Evaluation of the properties of the new complexes as catalysts for activation of 4-pentyn-1-ol towards formation of cyclization products showed that [PdCl2(Ph2NNC10H14O)}(2)] is more efficient than [PdCl2 (Me2NNC10H14O)(2)] which is one of the more efficient camphor derived catalysts reported before. In contrast the chelate complexes [Pd(YNC10H14O)(2)] (Y = MeN, PhN) display no catalytic activity. (C)2012 Elsevier B. V. All rights reserved.

The asymmetric carboalkoxyalkylidenation of 4-substituted cyclohexanones was effected by the use of chirally modified Horner-Wadsworth-Emmons (HWE) reagents in good yields (78-82%) as well as high levels of enantioselectivity (78-86% ee).
