Journal ArticleDOI
β-Ureido acids and dihydrouracils—VII
TL;DR: The coupling constants of the cis and trans isomers of 2-ureidocyclohexane carboxylic (UCHA) and of the erytho and threo isomer of 2,3-diphenyl-3-uridopropionic acid (DPhUPA) with gauche hydrogens are preferred as discussed by the authors.
Journal ArticleDOI
Thin-layer chromatography on silica gel as a method for assigning the relative configurations to some aliphatic diastereomeric compounds
TL;DR: In this paper, thin-layer chromatography on silica gel is proposed as a method for assigning the relative configurations of diastereomeric pairs of compounds of the above type.
Journal ArticleDOI
Optisches Drehungsvermögen und Konformation, IV. Über die Verhältnisse bei Ringschlußreaktionen epimerer 2‐Amino‐1.2‐diphenyl‐äthanole
TL;DR: In this article, the Brewster-Methode zeigt, das die grosere Anderung im Drehungsvermogen bei der Cyclisierung des erythro-Isomeren zum Morpholon-(5) durch die mit dem Ubergang einhergehende erhebliche Konformationsanderung bedingt ist.
Journal ArticleDOI
Absolute configurations of some 1,2-diphenylethane derivatives
N.D. Berova,Bogdan J. Kurtev +1 more
TL;DR: The absolute configurations of two series of genetically related compounds with a general formula PhCH(X) - CH(Y)Ph are determined by chemical correlation with 2,3-diphenylpropanoic acid (V).
Journal ArticleDOI
Heterocyclen mit Isochinolin‐Gerüst aus β‐Aminosäuren, 1 Synthese, Konfiguration und Konformation von (±)‐6.7‐Dialkoxy‐2‐methyl‐3‐aryl‐4‐methoxycarbonyl‐(und hydroxymethyl)‐1.2.3.4‐tetrahydro‐isochinolinen
Marietta Haimova,Mariana D. Palamareva,Bogdan J. Kurtev,Snežana I. Novkova,Stefan L. Spassov +4 more
TL;DR: In this paper, the trans-2-trans-3-aryl-4-methoxycarbonyl-tetrahydroiso-chinoline was shown to exist in CDCl3 predominantly in a half-chair conformation with equatorial-pseudoequatorial substituents at C-3 and C-4.
