STEREOCHEMISTRY AND VITALISM. [PDF]
Nature, 1898 ALTHOUGH Prof. Japp has already replied to the criticisms which have appeared in NATURE on his address to the Chemical Section of the British Association, we should be glad, in view of the interest taken in the matter, and also because we have been investigating externally compensated and optically active compounds for some years past, if you could ...

Stereocontrolled synthesis and nuclear magnetic resonance analysis of boranophosphate/phosphate chimeric oligonucleotides. [PDF]
R Soc Open SciThis report describes the stereoselective synthesis of boranophosphate/phosphate (PB/PO) chimeric oligodeoxynucleotides (ODNs) and the nuclear magnetic resonance (NMR) analysis of oligomers containing PB linkages.

Stereochemistry of the Brivaracetam Diastereoisomers. [PDF]
Chirality, 2016 AbstractThe stereochemistry of all four stereoisomers of brivaracetam was determined using vibrational circular dichroism (VCD) spectroscopy. By comparing experimentally obtained VCD spectra and computationally simulated ones, the absolute configurations can be confidently assigned without prior knowledge of their relative stereochemistry.

Unexpected Methyllanthionine Stereochemistry in the Morphogenetic Lanthipeptide SapT
Journal of the American Chemical Society, 2022 Lanthipeptides are polycyclic peptides characterized by the presence of lanthionine (Lan) and/or methyllanthionine (MeLan). They are members of the ribosomally synthesized and post-translationally modified peptides (RiPPs).

Stereochemistry of N-Acyl-5H-dibenzo[b,d]azepin-7(6H)-ones
Molecules, 2023 The stereochemical properties of N-acyl-5H-dibenzo[b,d]azepin-7(6H)-ones (2a–c), which inhibit potassium channels in T cells, were examined by freezing their conformational change due to 4-methyl substitution.
