Recent investigations from our laboratory have described compelling experimental evidence that Schiff-based pyridine, bipyridine (bipy), terpyridine (terpy), phenanthroline (phen), naphthyridine (naphthy) and pyridine-pyridazine (pyridaz) ligands exhibit a rich coordination chemistry towards transition metal complexes providing unusual coordination modes. This is well illustrated with bipy and phen frameworks which exhibit a bridging type of coordination compared to the classical chelating behaviour. In such a way metallo-helicates are produced in a straightforward manner. A similar helicoidal complex is prepared with the naphthy ligand while a tetranuclear tissue-like complex is obtained with the pyridaz frame. The stability constants for these copper(I) complexes were determined by spectrophometric titrations and global analytical techniques. Each step of the assembly process could be deciphered and the association constants of the final complexes are high. An important caveat of these studies is that positive cooperativity is not mandatory to obtain a helicate template as the final product. Judicious grafting of flexible and paraffinic tails to these multichelating ligands insure the formation of mesomorphic material after a selective metal-induced wrapping of the non-mesomorphic strands around the copper(I) cations. By careful design of the system either columnar or columnaro-smectic mesophases are observed at room-temperature. This simple approach of using Schiff-based scaffoldings which are easy to obtain in a pure form, also facilitates the extension of the size of the supramolecular assembly and the alteration of the molecular shape. Other metals such Ni(II), Fe(II), Cd(II) could be complexed easily which testify to the remarkable properties of this family of compounds. Finally, some consideration is given to the preparation of larger systems and their possible use in molecular based-devices.

The 1La and 1Lb classification of electronically excited states of cata-condensed hydrocarbons proposed by Platt in 1949 (Platt, J. R. J. Chem. Phys. 1949, 17, 484) is challenged by investigating a series of N-heteronaphthalenes and comparison of their low-lying pipi? excited states to those of naphthalene. The breakdown of Platt’s classification scheme for N-heterocycles is highlighted, and a reliable and versatile alternative using exciton analyses is presented. The strength of electron-hole correlation turns out to be the most reliable distinguishing feature, and thus, an alternative nomenclature of 1Lw (weakly correlated) and 1Ls (strongly correlated) is proposed. Furthermore, fundamental guidelines for their property modulation through N-atom substitution patterns are discussed.

The invention discloses a novel method for preparing chiral 3-morpholine methanol and 3-morpholine formic acid compounds. The method comprises the following steps: taking chiral serine as an initial material to obtain a serine ester (III) from a catalyst by esterification; reacting with halogen acetyl halide under an alkaline condition to obtain a compound (IV); obtaining a compound (V) by hydroxyl protection; adding a reducing agent to restore the ester into alcohol (VI); carrying out cyclization under the alkaline condition to obtain a compound (VII); obtaining a target product chiral 3-morpholine methanol compound (I) by amide reduction, hydroxyl deprotection and N protection; obtaining a chiral 3-morpholine formic acid compound (II) by oxidation. The method has the advantages of being low in cost, friendly to environment, simple to operate, high in yield, high in product purity and the like, the used reagent is simple and safe, and an intermediate in the reaction of each step does not need to be further purified, so that the experiment operation is greatly simplified, the production cost is reduced, and the method is applicable to industrial production.

Boron dipyrromethene type molecules (BODIPYs) are versatile molecules which have been used for applications ranging from photodynamic therapy to solar cells (DSSC). However, these molecules usually do not present high two-photon absorption cross-sections, limiting their use in nonlinear optical applications. Herein, we study a series of BF2-naphthyridine based boron-complexes with electron-donating and withdrawing groups to increase their two-photon absorption. We have found two-photon absorption cross-sections up to approximately 270 GM, which corresponds to an increase of approximately five times in comparison to the average cross-section value reported for molecules with similar conjugation length, indicating such compounds as potential materials for nonlinear applications in both the visible and infrared spectral regions.

100361-18-0, Name is 7-Chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic Acid, belongs to naphthyridine compound, is a common compound. HPLC of Formula: C12H8ClFN2O3In an article, once mentioned the new application about 100361-18-0.

A series of novel 6-fluoro-7-diazabicycloalkylquinolonecarboxylic acids substituted with various C8 (H, F, Cl, N) and N1 (ethyl, cyclopropyl, vinyl, 2-fluoroethyl, 4-fluorophenyl, 2,4-difluorophenyl) substituents, as well as, 9-fluoro-10-diazabicycloalkylpyridobenzoxazinecarboxylic acids, were prepared and evaluated for antibacterial activity against a range of important veterinary pathogenic bacteria. The diazabicycloalkyl side chains investigated at the 7-position (benzoxazine 10-position) include (1S,4S)-5- methyl-2,5-diazabicyclo[2.2.1]heptane (2), (1S,4S)-2,5- diazabicyclo[2.2.1]heptane (3), (1R,4R)-5-methyl-2,5- diazabicyclo[2.2.1]heptane (4), 8-methyl-3,8-diazabicyclo[3.2.1]octane (5), 9-methyl-3,9-diazabicyclo[4.2.1]nonane (6), 1,4-diazabicyclo[3.2.2]nonane (7), 1,4-diazabicyclo[3.3.1]nonane (8), and 9-methyl-3,9- diazabicyclo[3.3.1]nonane (9). Among these side chains, in vitro potency was not highly variable; other properties therefore proved more critical to the selection of possible development candidates. However, the relative potencies observed for several of these compounds in mouse, swine, and cattle infection models correlated well with those seen in vitro. A combination of the N1 cyclopropyl group and the C7 (1S,4S)-5-methyl-2,5-diazabicyclo[2.2.1]hept-2- yl appendage conferred the best overall antibacterial, physiochemical, and pharmacodynamic properties. Hence, danofloxacin (Advocin, 2c) (originally CP- 76,136, 1-cyclopropyl-6-fluoro-7-[(1S,4S)-5-methyl-2,5- diazabicyclo[2.2.1]hept-2-yl]-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid) was selected as a candidate for development as a therapeutic antibacterial agent for veterinary medicine.

The solvatochromism in 8-hydroxy-1,6-naphthyridin-5(6H)-one-7-carboxylic acid methyl ester (1), 5-hydroxy-1,7-naphthyridin-8(7H)-one-6-carboxylic acid methyl ester (2), and 4-hydroxy-2-methyl-1(2H)-isoquinolone-3-carboxylic acid methyl ester (3), has been studied in solvents of different polarity and hydrogen bond donor (HBD) and hydrogen bond acceptor (HBA) ability. The relative stabilities of isomers for these naphthyridine derivatives and their interaction with the solvent are reported. Two intramolecular hydrogen-bonded structures contribute to the ground state of compound 1. Temperature effects on the absorption bands were recorded to analyse the possible equilibrium between covalent and zwitterionic forms. The formation of zwitterionic species was observed only in HBD solvents, from which is inferred the solvent assistance in the proton transference. AM1 and PM3 semi-empirical calculations were used in support of the proposed interpretations.
