Novel diarylpyridinones, diarylpyridazinones and diarylphthalazinones as potential HIV-1 nonnucleoside reverse transcriptase inhibitors (NNRTIs)

In this Letter, we report on diarylpyridinone, diarylpyridazinone and diarylphthalazinone analogs as potential inhibitors of HIV-1 nonnucleoside reverse transcriptase (NNRTIs). The most promising compounds in these series are three diarylpyridazinones 25a, 25l and 25n which demonstrated submicromolar activity against wild-type HIV-1 and moderate activity against the single mutant strain Ba-L V106A.

Intramolecular fixation of t-butyl groups in thiolactim ethers influencing molecular conformation and the packing behavior

Derived from the result of a previous crystallographic study regarding an ethynylene bridged bispyrimidine, the presence of two intramolecular C-H…N hydrogen bonding contacts being responsible for a fixation of the terminal t-butylthio units to the azine nitrogens was noticed. Acting as stimulus, a series of different pyridine and pyridazine derivatives also featuring this unusual functionality has been synthesized and structurally studied. In order to support the investigations concerning this particular bonding pattern performed via X-ray structure analysis, calculations based on the density functional theory were carried out. It was found that the formation of the intramolecular hydrogen bonding motif has not only impact on the molecular stability but in some cases also predictably influences the reactivity and the packing behavior of the different heterocycles.

Medium-Ring Nitrogen Heterocycles through Migratory Ring Expansion of Metalated Ureas

Simple benzo-fused nitrogen heterocycles (indolines, tetrahydroquinolines, and their homologues) undergo migratory ring expansion through deprotonation of their benzylic urea derivatives with lithium diisopropylamide (LDA) in the presence of N,N?-dimethylpropylideneurea (DMPU). The products of the reactions are benzodiazepines, benzodiazocines, and their homologues, with ring sizes of 8?12. The reactions tolerate a range of substituent patterns and types, and may exhibit enantiospecificity or diastereoselectivity. Considerable complexity is rapidly generated in an efficient synthesis of these otherwise difficult-to-obtain medium-ring nitrogen heterocycles.

Deprotonative metalation of substituted benzenes and heteroaromatics using amino/alkyl mixed lithium-zinc combinations

Different homoleptic and heteroleptic lithium-zinc combinations were prepared, and structural elements obtained on the basis of NMR spectroscopic experiments and DFT calculations. In light of their ability to metalate anisole, pathways were proposed to justify the synergy observed for some mixtures. The best basic mixtures were obtained either by combining ZnCl 2¡¤TMEDA (TMEDA = N,N,N’,N’tetramethylethylenediamine) with [Li(tmp)] (tmp = 2,2,6,6-tetramethylpiperidino; 3 equiv) or by replacing one of the tmp in the precedent mixture with an alkyl group. The reactivity of the aromatic lithium zincates supposedly formed was next studied, and proved to be substrate-, base-, and electrophile-dependent. The aromatic lithium zincates were finally involved in palladium-catalyzed cross-coupling reactions with aromatic chlorides and bromides.

Synthesis, herbicidal activities, and 3D-QSAR of 2-cyanoacrylates containing aromatic methylamine moieties

A series of novel 2-cyanoacrylates containing different aromatic rings were synthesized, and their structures were characterized by 1H NMR, elemental analysis, and single-crystal X-ray diffraction analysis. Their herbicidal activities against four weeds and inhibition of photosynthetic electron transport against isolated chloroplasts (the Hill reaction) were evaluated. Both in vivo and in vitro data showed that the compounds containing benzene, pyridine, and thiazole moieties gave higher activities than those containing pyrimidine, pyridazine, furan, and tetrahedronfuran moieties. To further explore the comprehensive structure-activity relationship on the basis of in vitro data, comparative molecular field analysis (CoMFA) was performed, and the results showed that a bulky and electronegative group around the para-position of the aromatic rings would have the potential for higher activity, which offered important structural insights into designing highly active compounds prior to the next synthesis.
