    Stable sulfur ylides. X. Reactions of carbonyl-stabilized sulfonium ylides with acetyl chloride.
    摘要:
    高度稳定的磺阳离子二乙炔(1a-c)与氯乙酰反应生成了烯醇乙酸盐(2a-c)和烯醇二乙酸盐(3a-c)的混合物。类似地,磺阳离子乙酰碳甲氧基甲基化合物(5a,b)也生成了烯醇乙酸盐(6a,b)。这些烯醇乙酸盐在盐酸-甲醇的作用下进行了水解,生成了3-甲硫基-(3-苯硫基-)2,4-戊二酮(4a,b)或甲基2-甲硫基-(2-苯硫基-)乙酰乙酸盐(7a,b)。

  • Stable sulfur ylides. X. Reactions of carbonyl-stabilized sulfonium ylides with acetyl chloride.

    Highly stabilized sulfonium diacethylides (1a-c) reacted with acetyl chloride to give a mixture of the enol acetates (2a-c) and the enol diacetates (3a-c). Similarly, sulfonium acetylcarbomethoxymethylides (5a, b) gave the enol acetates (6a, b). These enol acetates were hydropyzed with HCl-MeOH to give 3-methylthio- (3-phenylthio-)2, 4-pentanediones (4a, b) or methyl 2-methylthio- (2-phenylthio-)acetoacetates (7a, b).

    methodology has been developed for the regioselective sulfenylation of pyrazolo[1,5-a]pyrimidine derivatives. Rose bengal, blue LEDs, KI, K2S2O8, and DMSO are all essential for this photocatalytic transformation. The protocol is applicable for the synthesis of a library of 3-(aryl/heteroaryl thio)pyrazolo[1,5-a]pyrimidine derivatives with broad functionalities. The selectivity and scalability of the methodology

    日期:——
    When treated with hydrazine, metal beta-diketonates undergo decomposition to form the corresponding pyrazoles, irrespective of the kinetic stability of the chelates. With substituted metal chelates, the main reaction products are pyrazoles bearing in position 4 the gamma-substituent of the compex. Other products are formed when the substituent has centers sensitive to nucleophilic substitution and/or elimination. The reaction can be used for structural assessment of the starting beta-diketonate.
  • Nitrogen-containing heterocycles from metal β-diketonates
    作者:I. V. Svistunova、N. P. Shapkin、O. V. Nikolaeva、O. A. Apanasenko
    DOI:10.1134/s1070363211040244
    日期:2011.4
    Factors determining the reaction of metal beta-diketonates with hydrazine, in particular the nature of central metal ion and structure of beta-diketonate ligand, are discussed. The possibility for the preparation of other heterocyclic compounds via reaction of metal acetylacetonates with phenylhydrazine, o-phenylenediamine, urea, and thiourea was studied.
