A high-yielding and diastereoselective route to biologically significant 2-aryl- and 2-alkyl-3-amido dihydroquinolones has been developed in up to 90 : 10 e.r. by employing a novel Lewis acidic BINOL-derived copper(ii) catalyst.
This invention relates to novel hydroxyethylamino sulfonamides, their derivatives, pharmaceutically acceptable salts thereof. This invention also provides compositions comprising a compound of this invention and the use of such compositions in methods of treating diseases and conditions that are beneficially treated by administering a compound with the ability to act as an HIV (human immunodeficiency virus) protease inhibitor.

A polymer blend is provided of a fluoropolymer and a liquid crystal polymer. The blend is achieved using a compatibilizer composition that contains a copolymer having a fluorine-containing monomer and a liquid crystal monomer.
meso (1), optically pure (2), and racemic (3) ligand types of [Fe(pybox)2]2+ complexes. Their magnetic susceptibilities were measured via temperature-dependent paramagnetic 1H NMR spectroscopy. We fitted the midpoint temperatures of the transition (T1/2) of 260 K for 1(ClO4), 247 K for 2(ClO4), and 281 K for 3(ClO4). The influence of structural symmetry on spincrossover was rationalized through density
