Diastereomers and Low-Temperature Oxidation

The Journal of Physical Chemistry A, 2021
Diastereomers have historically been ignored when building kinetic mechanisms for combustion. Low-temperature oxidation kinetics, which continues to gain interest in both combustion and atmospheric communities, may be affected by the inclusion of diastereomers in radical chain-branching pathways.

Chromatographic behaviour of diastereomers

Journal of Chromatography A, 1977
For diastereomers of the types RM values on silica gel are investigated as a function of the mole fraction of the more polar solvent in binary solvent systems, according to Soczewinski's method. The correlation between RF and pKa is discussed, and thin-layer chromatographic comparison between acyclic and cyclic compounds is made.

Synthesis of diastereomers of sarcolysylleucine

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1978
1. The diastereomers of sarcolysylleucine with a formylated and free amino group in sarcolysine residue were obtained by using the N-ethoxycarbonyl-2-ethoxy-1, 2-dihydroquinoline method to form the peptide linkage. 2. The possibility of deformylating peptides, containing the di-2-chloroethyl group, by hydrazine acetate was studied.

Ciguatoxin-2 is a diastereomer of ciguatoxin-3

Toxicon, 1993
Ciguatoxin-2, a major ciguatoxin present in the flesh and viscera of ciguateric fishes, has been shown by 1H nuclear magnetic resonance studies (2-dimensional homonuclear Hartman Hahn, nuclear Overhauser effect and decoupling difference experiments) to be a diastereomer of ciguatoxin-3, differing only in stereochemistry at carbon 52 (a quaternary ...

On the Chemistry of the Resveratrol Diastereomers

Monatshefte f�r Chemie / Chemical Monthly, 2003
The (E)- and (Z)-diastereomers of resveratrol were investigated with respect to their photochemical and thermal diastereomerization reactions. The free enthalpy difference between the two diastereomers was estimated to be in the order of common stilbenes, with the (E)-diastereomer more stable by about 11–14 kJ mol−1. The Arrhenius activation barrier of
