Iridium complexes of chiral oxazoline-based P,N-ligands provedto be efficient catalysts for the enantioselective hydrogenationof 2-aryl- and 2-alkyl-4 H-chromenes.The best results were obtained with a ligand derived from threonine(ThrePHOX), which in

Treatment of 1,9-bis(lithiocyclopentadienyl)nonane (8b) with ZrCl4(THF)2, in dilute solution, gave the crystalline mononuclear “large” ansa-metallocene 3b (7% isolated). The X-ray crystal structure analysis of 3b revealed a metallocene conformati

A series of chiral phosphinite-oxazolines was synthesized in four steps starting from carboxylic acids and threonine methyl ester. In the asymmetric hydrogenation of a number of alkenes, iridium complexes of these ligands induced significantly higher

Asymmetric hydrogenation of olefins is one of the most useful reactions for the synthesis of optically active compounds, especially in industry. However, the application range of the catalysts developed so far is limited to alkenes with a coordinatin
