  Reactivity of 3-formyl- and 3-cyanothiochromones toward some N- and C-nucleophiles. Novel synthesis of 3-substituted 2-aminothiochromones

  摘要：

  The reactions of 3-formylthiochromone with o-phenylenediamines, o-aminobenzenethiol, and indoles proceeded at the aldehyde group to give 3-(benzimidazol-2-yl)thiochromone, 3-(benzothiazol-2-yl) thiochromone. and 3-di(indol-3-yl)methylthiochromones, respectively. 3-Formyl- and 3-cyanothiochromones react with primary aromatic amines and phenylhydrazine to give the corresponding anils and phenylhydrazones of 3-formyl- and 2-amino-3-formylthiochromones. The reaction of 3-cyanochromones with o-phenylenediamines gave 2-amino-3-[(2-aminophenyl)iminomethyl]-4H-chromen-4-ones. (C) 2010 Published by Elsevier Ltd.

• Oxidative formylation and chloromethylation in Vilsmeier reactions of O- and S-heterocyclic ketones

  The action of DMF-POCl3 at 20 °C on tetrahydro-4H-pyran-4-one, tetrahydro-4H-thiopyran-4-one, chroman-4-one, and thiochroman-4-one affords the corresponding β-chlorovinylaldehydes. However, with excess DMF-POCl3 at 100 °C, chroman-4-one affords 3-(chloromethyl)chromone, and thiochromanone gives 3-formylthiochromone. Mechanistic rationalisations are provided.

  DMF-POCl 3在20°C下对四氢4 H-吡喃-4-酮，四氢4 H-硫代吡喃-4-酮，苯并吡喃-4-酮和硫代苯并吡喃-4-酮的作用提供了相应的β -氯乙烯基醛。但是，在100°C下使用过量的DMF-POCl 3时，苯并二氢吡喃-4-酮可制得3-（氯甲基）苯并二氢吡喃酮，而硫代苯并二氢吡喃酮可制得3-甲酰基硫代色酮。提供了机械合理性。

  carboxaldehydes and boron trihalides (BX3, X=F, Cl, Br, I) is described. A diverse array of halofunctionalized indenes substituted with a heterocycle has been synthesized regioselectively with BX3 as a promotor for the carbocyclization and a source of X− for halogenation. This reaction proceeds via a formal halogenative [4+1] cycloaddition between arylalkynes and carboxaldehydes promoted by boron trihalides to generate

• Photochromic properties of cationic merocyanine dyes. Thermal stability of the spiropyran form produced by irradiation with visible light

  A series of novel cationic merocyanine dyes were prepared by condensation of 1,2,3,3-tetramethylindolium derivatives and 3-formyl-4H-1-benzothiopyran or -benzopyran derivatives, and their photochromic properties were investigated, especially focusing on the substituent effect in the indolium moiety. These dyes were converted into the spiropyran (SP) form so as to be colorless by irradiation with visible light, although, left under darkness, the colored merocyanine (MC) form was reproduced. The thermal coloration was affected by two factors: the substituent in the indolium moiety and the counter anion. An electron-donating substituent such as a methoxy group at the 5 position effectively retarded the thermal coloration, whereas an electron-withdrawing group such as a nitro group accelerated it. These substituent effects afforded good linearity for the Hammett rule with para σ parameters, indicating that decrease of the electron density in the indoline moiety of the SP form facilitated heterolytic cleavage of the bond between the spiro carbon and the oxygen of the pyran ring.

  通过缩合反应制备了一系列新型阳离子型部花青染料，该反应涉及1,2,3,3-四甲基吲哚鎓衍生物与3-醛基-4H-1-苯并噻吡喃或苯并吡喃衍生物的反应，并研究了它们的光致变色性质，特别关注吲哚鎓部分中的取代基效应。这些染料在可见光照射下转化为无色的螺吡喃（SP）形式，尽管在黑暗环境中，带色的部花青（MC）形式会再次出现。热致变色受到两个因素的影响：吲哚鎓部分的取代基和反荷离子。在5位带有供电子取代基（如甲氧基）有效地延缓了热致变色，而吸电子基团（如硝基）则加速了热致变色。这些取代基效应提供了良好的Hammett规则线性关系，对应于para σ参数，表明在SP形式中吲哚部分电子密度降低促进了螺碳与吡喃环氧之间键的异裂解离。

  synthetic relevance of the polyhalogenated compounds obtained was demonstrated by the synthesis of several new heterocycles. An aromatization via a halogenation–dehydrohalogenation sequence proved to be a rewarding synthetic route to 2-(fluoroacyl)phenols and previously unknown 3-(fluoroacyl)thiochromones. The structure of one of the synthesized compounds was confirmed by X-ray diffraction analysis

  3-Substituted 2-phenyl-4H-1-benzothiopyran-4-ones (thioflavones) were prepared to test antimicrobial activity. It was found that 3-(phenyl)thiochromone derivatives (isothioflavones) were prepared by the Meerwein reaction of thiochromone with p-nitrobenzenediazonium ion. 3-(Formyl)thioflavone exhibits weak antimicrobial activity against Trichophytons and Candida.
