Stereochemical dependence of 3J CH coupling constants in 2-substituted 4-t-butyl-cyclohexanone and their alcohol derivatives
(American Chemical Society, 2011-11)
Theoretical and experimental studies on 3J C2H6eq NMR spin - spin coupling constants in both the 2-X-4-t-butyl-cyclohexanone (X = H, CH 3, F, Cl, and Br) and in their alcohol derivatives series are reported. Results thus ...
Stereochemical transfer to atmospheric aerosol particles accompanying the oxidation of biogenic volatile organic compounds
(AMER GEOPHYSICAL UNION, 2011)
Asymmetric emission profiles of the stereoisomers of plant-derived volatile organic compounds vary with season, geography, plant type, and stress factors. After oxidation of these compounds in the atmosphere, the low-vapor ...
Stereochemical dependence of NMR geminal spin-spin coupling constants
(John Wiley & Sons Ltd, 2008-12)
In this work it was sought to explore the versatility of germinal spin–spin coupling constants, ²JxySSCCs, as probes for stereochemical studies. A set of compounds, where their experimental ²JxySSCCs through the X–C–Y ...

Stereochemical Dependence of (3)J(CH) Coupling Constants in 2-Substituted 4-t-Butyl-cyclohexanone and Their Alcohol Derivatives
(Amer Chemical SocWashingtonEUA, 2011)
Synthesis of new cyano-substituted analogues of Tröger's bases from bromo-derivatives. A stereochemical dependence of long-range ( n J HH , n = 4, 5, and 6) proton-proton and proton-carbon ( n J CH , n = 1, 2, 3, 4, and 5) coupling constants of these compounds
(John Wiley & Sons Ltd, 2019-04)
A free-catalyst microwave-assisted cyanation of brominated Tröger´s base derivatives (2a-f) is reported. The procedure is simple, efficient and clean affording the nitrile compounds (3a-e, I) in very good yields. Complete ...
Pharmacokinetic implications associated to the use of drugs as racemates or pure enantiomers Implicancias farmacocinéticas asociadas al uso de fármacos como racematos o enantiómeros puros.
(1995)
This article critically reviews the recent specialized literature concerning the influence of the stereochemical nature of quiral drugs on the pharmacokinetic processes and its pharmacological implications. Evidence is ...
