The synthesis of new optically pure ferrocenyl diphosphines have been realized from (R)-(+)-N,Ndimethylaminoethylferrocene. Particularly, dissymmetric ferrocenyl diphosphines have been synthesized. The diphosphines have been used as ligands in asymmetric transfer hydrogenation of acetophenone in the presence of Ru catalysts. © 2006 Elsevier Science.

The palladium (II)-catalysed reactions of alkenols and aminoalkenols such as oxycarbonylations or bicyclisations are powerful methods for the construction of oxygen and nitrogen-containing heterocyclic compounds. This review highlights recent progress in the development of the asymmetric palladium(II)-catalysed Wacker-type cyclisations of unsaturated polyols and aminoalcohols. The scope, limita...

this study reports the synthesis of chitosan anchored schiff base, ([2-oxo-1h-indol-3-ylidene] amino) chitosan and its cu (ii) metal complex. the complex was characterized by elemental analysis, ft-ir spectrum, thermogravimetry analysis .the crystallinity of the compound was analyzed by powder x-ray diffraction technique. the catalytic efficiency of complex was studied in the oxidation of alcoh...

For the first time we have been able to employ enantiopure 1,2-amino alcohols derived from abundant amino acids in C−C bond-forming hydrogen-borrowing alkylation reactions. These reactions are facilitated by use of aryl ketone Ph*COMe. Racemisation amine stereocentre during can be prevented sub-stoichiometric base and protection nitrogen with a sterically hindered triphenylmethane (trityl) or b...

Aliphatic primary amines are a class of chemical feedstock essential to the synthesis of higher-order nitrogen-containing molecules, commonly found in biologically active compounds and pharmaceutical agents. New methods for the construction of complex amines remain a continuous challenge to synthetic chemists. Here, we outline a general palladium-catalysed strategy for the functionalization of ...
