Despite many efforts, one of the smallest heterocycles containing two nitrogen atoms, pyridazine, could not be converted to its N,N-dioxide (see, however, Nakadate et al. Chem. Pharm. Bull. 1970, 18, 1211-1218). HOF·CH3CN, made easily from diluted fluorine, was able to accomplish this task in a fast reaction with good yields.

The preparation of the glycopeptidolipid (GPL) present in the cell wall of Mycobacterium avium Serovar 4, namely 3,4-di-O-Me-alpha-L-Rhap-(1? 1){R-C21H43CH(OH)CH2CO-D-Phe-[4-O-Me-alpha -L-Rhap-(1?4)-2-O-Me-alpha-L-Fucp-(1?3)-alpha-L-Rhap-(1?2) -6-deoxy-alpha-L-Talp-(1?3)]-D-allo-Thr-D-Ala-L-Alaol}(1), is described. The synthesis was based on the disconnection of the final structure into four building blocks, an L-rhamnosyl pseudodipeptide, a 6-deoxy-L-talosyl dipeptide, a trisaccharide donor, and a 3-hydroxyalkanoic acid. The key steps are the creation of the glycosidic linkage between the trisaccharide donor, used as a pentenyl glycoside, and the 6-deoxy-L-talose unit of an appropriate D-Phe-O-(6-deoxy-L-talosyl)-D-allo-Thr derivative and the final coupling of the two glycodipeptide fragments. Pentenyl glycosides were shown to provide useful donors in several glycosylation steps. This work constitutes the first synthesis of the full structure of a so-called “polar mycoside C” GPL.

932-22-9, Name is 4,5-Dichloro-3(2H)-pyridazinone, belongs to pyridazine compound, is a common compound. category: pyridazineIn an article, once mentioned the new application about 932-22-9.

We report the design and synthesis of a new class of piperazine- pyridazinone analogues. The arylpiperazine moiety, the length of the spacer, and the terminal molecular fragment were varied to evaluate their influence in determining the affinity of the new compounds toward the alpha1- adrenergic receptor (alpha1-AR), alpha2-adrenergic receptor (alpha2-AR), and the 5-HT1A serotoninergic receptor (5-HT1AR). Biological data showed that most of the compounds have an alpha1-AR affinity in the nanomolar or subnanomolar range, while affinity toward the other two receptors was lower in most cases. However, several of the tested compounds also showed very good (in the nanomolar range) or moderate affinity toward the 5-HT1AR subtype.

Histamine H3 receptor (H3R) inverse agonists that have been in clinical trials for the treatment of excessive sleep disorders, have been plagued with insomnia as a mechanism-based side effect. We focused on the identification of compounds that achieve high receptor occupancy within a short time, followed by rapid disengagement from the receptor, a target profile that could provide therapeutic benefits without the undesired side effect of insomnia. This article describes the optimization work that led to the discovery of 1-(1-methyl-6-oxo-1,6-dihydropyridazin-3-yl)piperidin-4-yl 4-cyclobutylpiperazine-1-carboxylate (18 b, LML134).

Synthetic Route of 141-30-0, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 141-30-0, molcular formula is C4H2Cl2N2, introducing its new discovery.

The OsO4-cinchona alkaloid catalyzed asymmetric dihydroxylation process has been applied successfully to the kinetic resolution of 1-substituted allylic alcohols by the use of the 4-methoxybenzoyl derivatives in conjunction with the specifically designed DHQD-PYDZ-(S)-anthryl catalyst (5 · OsO4). Thus, (±)-3-buten-2-yl 4-methoxybenzoate (4a) and (±)-1-phenyl-2-propen-1-yl 4-methoxybenzoate (4b) have been kinetically resolved with relative rate constants of 20 and 79, respectively. These values are among the best reported for the kinetic resolution of racemic compounds using non-enzymatic catalyst systems. The design of this resolution process was accomplished under mechanistic guidance using the transition state model proposed recently for the asymmetric dihydroxylation process. The specially selected ligand 5 possesses a deep U-shaped binding pocket with both the methoxyquinoline and the 1-anthryl walls projecting rearward of the pyridazine linker group at the floor. This catalyst not only recognizes the 4-methoxybenzoyl group of these substrates, which extends into the distant binding pocket of the catalyst, but also provides an open space adjacent to one of the allylic alpha-substituents of the substrate which allows for enantiomeric selection in the dihydroxylation. The magnitude of the kinetic resolution and the absolute stereopreference for the dihydroxylation reaction provide strong evidence for the guiding mechanistic model. The utility of this process is clearly demonstrated by the selective dihydroxylation of 1,4-pentadien-3-yl 4-methoxybenzoate (10) to give diol 11 in 70% isolated yield with >98% ee and >96% de.
