Pharmacokinetics of the enantiomers of thalidomide

, 1997
Thalidomide has a chiral center and the racemate of (+)-(R) and (-)-(S)-thalidomide was introduced as a hypnotic/sedative drug in 1957. In 1961 it was withdrawn due to teratogenicity and neuropathy. There is a growing interest in thalidomide treatment of

Substituent‐Controlled Ring Opening of 1‐Substituted Benzocyclobutenes: Electronic Structure and Diradical Character of Ortho‐Quinodimethane Intermediates

Chemistry – A European Journal, EarlyView.
Experimental and computational studies elucidate how the electronic nature of substituents controls the ring‐opening temperature and diradical character of 1‐substituted benzocyclobutenes, enabling the rational design of o‐quinodimethane‐based synthetic transformations.

Solvent‐Driven Conformational Landscapes of a Tetradentate Schiff Base Ligand and Its Metal Complexes: A Genetic Algorithm–Guided VCD Investigation

Chemistry – A European Journal, EarlyView.
Solvent effects: vibrational circular dichroism (VCD) revealed pronounced solvent‐induced conformational shifts for a tetradentate salen ligand in CDCl3, a solvent generally considered benign. Contrary to the DFT prediction of a single dominant conformer family, quantum cluster growth together with the genetic algorithm guided VCD analysis uncovered ...

Modular Rh‐Catalyzed Synthesis and Biological Profiling of Diverse Pentafluorobenzenesulfonamide Reactive Fragments

Chemistry – A European Journal, EarlyView.
A modular Rh‐catalyzed synthetic approach enabled the preparation of diverse reactive fragments from available substrates. The reactive fragments modified Aurora A kinase via several distinct modification reaction classes. In a complex biological environment, the constellation of modified proteins depended critically on the reactive fragment structure.

The Asymmetric Self‐Replicative Alkylation of N‐Arylaldimines Using Organolithium Reagents

Chemistry – A European Journal, EarlyView.
Here, we report a new asymmetric autoinductive reaction; the addition of nBuLi to N‐arylaldimines to form chiral lithium amides. The reaction proceeds with full conversion and complete transfer of chirality, representing the first example of an asymmetric autoinductive reaction with organolithium reagents.
