Recent advances in computing heteroatom-rich five- and six-membered ring systems

Recent developments in computer technology and the increasing efficiency and accuracy of current ab initio and density functional programs allow the investigation of increasingly complex systems. Molecules that could be treated only at the semiempirical level ten years ago can now be computed at the density functional or the MP2 level with basis sets of double-zeta quality. Very often, these calculations are accurate enough to explain experimental findings, and consequently many experimental studies are augmented by quantum chemical calculations. However, in many cases just a few kilocalories per mole may decide between different reaction mechanisms, different explanations of physical effects, or even a preferred tautomer or conformer. Since the inherent errors of MP2 and DFT calculations are still significantly larger than chemical accuracy, high-level calculations are mandatory for many problems. This holds particularly true for the investigation of reaction barriers involving bond-breaking processes. Although these problems have been recognized by many investigators, a substantial number of papers lack sufficient accuracy. This accuracy problem appears to be more severe for heteroatom-rich species than for other systems, in particular for systems with adjacent heteroatoms. However, DFT calculations were found to cope surprisingly well with the geometric parameters of most of these systems. As is common in heterocyclic chemistry, many studies concern tautomeric equilibria. While quantum chemical calculations are straightforward for the question of the most stable isomer, experiments are sometimes very demanding. Therefore, quantum chemistry can easily provide answers that may require substantial experimental effort. Comparatively few studies concern the investigation of entire reaction paths. This is much more demanding than computing a limited number of tautomers, of course, but usually provides a very detailed picture of the reaction mechanism. In certain cases, it was only possible to judge the nature of a chemical reaction on the basis of quantum chemical calculations. Most studies concerning pyrimidines originate from biochemical questions. Since these systems are dominated by hydrogen-bonding and/or dispersion contributions, methods beyond the Hartree-Fock level are mandatory. The success of quantum chemical studies in this field is impressive and many effects could be explained on the basis of these theoretical investigations.

5-Substituted-N-pyridazinylbenzamides as potent and selective LRRK2 inhibitors: Improved brain unbound fraction enables efficacy

We describe the discovery and optimization of 5-substituted-N-pyridazinylbenzamide derivatives as potent and selective LRRK2 inhibitors. Extensive SAR studies led to the identification of compounds 18 and 23, which demonstrated good in vitro pharmacokinetic profile and excellent selectivity over 140 other kinases. Both compounds demonstrated high unbound fractions in both blood and brain. Compound 18 proved to be brain penetrant, and the high unbound fraction of compound 18 in brain enabled its in vivo efficacy in CNS, wherein a significant inhibition of LRRK2 Ser935 phosphorylation was observed in rat brain following intravenous infusion at 5 mg/kg/h.

alpha-Chlorobenzylation of Nitroarenes via Vicarious Nucleophilic Substitution with Benzylidene Dichloride: Umpolung of the Friedel-Crafts Reaction

Readily available alpha,alpha-dichlorotoluenes enter a vicarious nucleophilic substitution (VNS) reaction with electron-deficient arenes to give alpha-chlorobenzylated nitrobenzenes, as well as six- and five-membered heterocycles. Oxidation of the initially formed alpha-chlorobenzylic carbanions instead of protonation results in formation of diaryl ketones, providing a means for overall nucleophilic C-H benzoylation of electron-deficient aromatic rings. Alternatively, benzoylated nitroarenes can be obtained via the reaction of isolated alpha-chlorodiarylmethanes with sodium azide.
