Ammonium ylides derived from the Cu(II)-catalyzed decomposition of alpha-diazo carbonyls tethered to tertiary amines underwent a benzylic Stevens [1,2]-rearrangement to give tetrahydroisoquinolines or benzazepines containing fused five-membered rings, a feature found in the cephalotaxus alkaloids. Model studies were also carried

A new approach to synthesize optically active β-amino-α-hydroxyl acid derivatives via chiral Brønsted acid-Rh(2)(OAc)(4) cocatalyzed three-component reactions of diazo acetates with alcohols and imines is reported. A matched reaction system was identified to give the products in moderate diastereoselectivity and

In our study, we have determined the thermodynamic behavior for the replacement reaction of one and two acetyl-ligands from the diaqua-tetrakis(mu-acetylato)dirhodium(II,II) complex by purine DNA bases. The complexes were optimized at the density functional theory (DFT) level with the B3LYP

The interaction of Rh2(OAc)4 with human serum albumin (HSA) has been studied by absorption difference spectroscopy, CD spectroscopy, and quantitative precipitating HSA-antibody test. Our results demonstrate that this rhodium complex reacts easily with HSA at several ratios of reagents. The
