Host–Guest Assembly of a Molecular Reporter with Chiral Cyanohydrins for Assignment of Absolute Stereochemistry

Chemistry - A European Journal, 2016
The absolute stereochemistry of cyanohydrins, derived from ketones and aldehydes, is obtained routinely, in a microscale and derivatization-free manner, upon their complexation with Zn-MAPOL, a zincated porphyrin host with a binding pocket comprised of a

Assigning Stereochemistry to Single Diastereoisomers by GIAO NMR Calculation: The DP4 Probability

Journal of the American Chemical Society, 2010
GIAO NMR shift calculation has been applied to the challenging task of reliably assigning stereochemistry with quantifiable confidence when only one set of experimental data are available.

Effects of stereochemistry and copolymerization on the LCST of PNIPAm.

Journal of Chemical Physics, 2017
Poly(N-isopropylacrylamide) (PNIPAm) is a smart polymer that presents a lower critical transition temperature (LCST) of 305 K. Interestingly, this transition point falls within the range of the human body temperature, making PNIPAm a highly suitable ...

STEREOCHEMISTRY IN ANAESTHESIA

Clinical and Experimental Pharmacology and Physiology, 1997
SUMMARY1. Interest in the pharmacokinetic and pharmacodynamic properties of the enantiomers of chiral drugs has greatly increased in recent years. This is particularly so for agents used in anaesthesia.2. Chiral compounds are those that can exist in two non‐superimposable forms. Each form is termed an enantiomer or stereoisomer.

The stereochemistry of pinidine

Tetrahedron, 1965
Abstract The stereochemistry of pinidine, a piperidine alkaloid from Pinus sabiniana, was established by chemical and spectroscopic methods as 2-(R)-methyl-6-(R)-(2-trans-propenyl)-piperidine (XXI). Some interesting rearrangements which occurred during degradative studies are discussed, and the configuration of pinidine is compared with that of ...

Reinvestigation of the stereochemistry of the C-glycosidic ellagitannins, vescalagin and castalagin.

Organic Letters, 2015
The stereochemistry of the C-glycosidic ellagitannins, vescalagin and castalagin, has been reinvestigated using computational methods. DFT calculations of their (1)H and (13)C NMR spectra, as well as TDDFT calculations of the ECD spectra of their des ...
