4-Hydroxy-2-alkenals and other products formed by water-mediated oxidative decomposition of .alpha.,.beta.-unsaturated aldehydes
Autor: Manfred Huffer, Gerhard Scheller, Peter Schreier, Bertram. Grein
Publikováno v: Journal of Agricultural and Food Chemistry. 41:2385-2390
Water-mediated (pH 6.5) model experiments were carried out with (E)-2-hexenal (1), (E)-2-octenal (2), and (E,E)-2,4-decadienal (3) under oxygen atmosphere. After complete degradation of the alpha,beta-unsaturated aldehydes 1-3 and solvent extraction

Lipase-catalyzed transesterification in organic solvents: Preparation and enantiodifferentiation of optically enriched 4(5)-alkylated 1,4(1,5)-olides
Autor: Peter Schreier, Manfred Huffer
Publikováno v: Tetrahedron: Asymmetry. 2:1157-1164
Porcine pancreatic lipase (PPL) catalyzed intramolecular transesterification of n-propyl esters of 4(5)-hydroxyalkanoic acids (C 5 C 12 ) in diethyl ether (20°C) yielded (S)-4-alkylated 1,4-olides of high optical purity (ee > 80%) and optically p

Chirality Evaluation of 2-Heptanol and Z-4-Hepten-2-ol from Banana Fruit Using Multidimensional Gas Chromatography
Autor: Peter Schreier, Manfred Huffer, Otmar Frohlich
Publikováno v: Zeitschrift für Naturforschung C. 44:555-558
A polar fraction obtained from banana fruit pulp by high-vacuum distillation / solvent extraction (pentane-dichlorom ethane, 2 + 1) and subsequent liquid chromatography on silica gel was derivatized with isopropylisocyanate. Separation of enantiom er
