摘要:Abstract(#br)Dimethyl, diethyl and dipropyl esters of ( Z ) - and ( E )-2-methyl-butenedioic acids (citraconic and mesaconic acid) were hydrolysed by pig live esterase, PLE. For the diethyl esters the enzyme showed low regioselectivity for both the ( Z )- and the ( E )-isomers. H...

摘要:Abstract(#br)A short, technically feasible route was developed for the synthesis of ( S )2-(4-fluorophenyl)-3-methylbutanoic acid (S)- 2 with an overall yield of 80% starting from 4-fluorophenylacetic acid. Asymmetric hydrogenation of the easily accessible unsaturated acid 3 in t...

摘要:Abstract(#br)Levels of nine selected polycyclic aromatic hydrocarbons, PAHs, in surface soils from areas in southern and central Norway are presented. Levels in central Norway are generally low, while the southern Norway soils are about ten-fold higher with respect to 4 and 5 rin...

摘要:Abstract(#br)In a better procedure than the known for (rac)- 2a , the diamine (rac)- 2b was resolved for the first time with the new resolving agent ( R , R )- and ( S , S )-2,3-di(phenylamino-carbonyl)tartaric acid ( 5c ) (40–45% weight yields; >99% ee). The diamines ( R )-...

摘要:Abstract(#br)The new amidophosphine-phosphinite (AMPP) ligands 4a – g (called tLANOP ligands) derived from the chiral hydroxy amide ( R )- or ( S )-2-hydroxy-3,3, N -trimethylbutyramide have been prepared in 48–83% yield. The crystal structures of the square planar complexes...

摘要:Abstract(#br)The effects of viscosity v and reaction rate k on the Riemann solutions of Navier-Stokes equations for a reacting gas are analyzed numerically. In this numerical experiment, a set of Riemann initial values is designed, such that only detonation can occur under t...

摘要:Abstract(#br)Stable cationic carotenoid aggregates — predominantly of the J -type — develop when the hydrochlorides of carotenoid aldoximes and ketoximes are exposed to water. The oxime hydrochlorides are obtained by simple syntheses from commercially available food color ca...

摘要:Abstract(#br)The electrochemical potential difference of sodium (sodium gradient) across cell membranes is the energy source of a number of important cellular functions, and failure to maintain the gradient is likely to affect these functions. The present investigation shows that...
