Iridium-Catalyzed Asymmetric Hydrogenation of Unsaturated Piperazin-2-ones

Two different iridium catalyst systems, generated from the ruthenocene-based phosphine-oxazoline ligand tBu-mono-RuPHOX or the diphosphine ligand BINAP, were developed for the asymmetric hydrogenation of 5,6-dihydropyrazin-2(1H)-ones, affording chiral piperazin-2-ones in good yields and with moderate to good ees. Different catalytic behaviors for the hydrogenation of these types of substrate were observed with these two catalyst systems. Our tBu-mono-RuPHOX ligand, which bears a ruthenocene scaffold with planar chirality, was found to be the best ligand for the [Ir(L)(COD)]BArF catalyst system, affording the desired products with up to 94% ee.

Direct conversion of aromatic ketones to arenecarboxylic esters via carbon-carbon bond-cleavage reactions

Aromatic methyl ketones, ss-keto esters, and trifluoromethyl-l,3- diketones can be directly converted to arene-carboxylic esters via carbon-carbon bond cleavage of pyridinium iodide intermediates in the presence of copper(II) oxide, iodine, pyridine, and potassium carbonate in alcoholic media. The advantages of the present method in terms of good yields, mild reaction conditions, and inexpensive reagents should make this protocol a valuable alternative to the existing methods.

Reactions of diazoalkanes with molybdenum peroxide

The reactions of diazoalkanes with MoO5·HMPA·H2O caused both oxidation into carbonyl compounds and metal carbenoid insertion reaction with methanol to give methyl alkyl ethers. These reaction paths are affected by the substituent of diazoalkanes.
