  • Pathways of decomposition of N-cyclopropyl N nitrosoureas in methanol
    作者:I. P. Klimenko、Yu. V. Tomilov

    日期:2005.2
    Decomposition of a series of N-cyclopropyl-N-nitrosoureas (CNU) in CD3OD was studied. These decompose much more rapidly than N-methyl-N-nitrosourea, one of the decomposition pathways being denitrosation, which is atypical of alkylnitrosoureas under the reaction conditions used. The nature of substituents in the cyclopropane ring has a great effect on the stability of CNU and the product ratio. In the presence of H2 SO4, decomposition occurs much more rapidly. Possible pathways of the formation of the major decomposition products of CNU are proposed based on the experimental data.
    对一系列N-环丙基-N-亚硝基脲(CNU)在CD3OD中的降解进行了研究。它们的降解速度远快于N-甲基-N-亚硝基脲,其中一个降解途径是脱亚硝基化,这在所用反应条件下对烷基亚硝基脲而言是不典型的。环丙烷环中取代基的性质对CNU的稳定性和产物比具有很大影响。在H2SO4存在下,降解速度大大加快。根据实验数据,提出了CNU主要降解产物形成的可能途径。

    A reaction of cyclopropanediazonium ion, generated by decomposition of N-cyclopropyl-N-nitrosourea upon treatment with potassium or cesium carbonates, with various poly-hydroxyarenes and aminophenols has been studied. The reaction of azo-coupling proceeds with phloroglucinol, resorcinol, 3-methoxy- and 3-aminophenol giving rise to mono-, bis-, and tris(cyclopropylazo)arenes as the major products. Oxidizable phenols such as hydro-quinone, 2-methoxy-, 4-amino-, and 2-aminophenol give products of radical transformations with participation of cyclopropyl radical.

  • Formation and reactions of substituted diazocyclopropanes and cyclopropyldiazonium ions
    作者:I. P. Klimenko、Yu. V. Tomilov、O. M. Nefedov

    日期:2004.1
    Decomposition of N-nitroso-N-cyclopropylureas at 5—7 °C on treatment with K2CO3 containing 15—20% H2O allows simultaneous generation of both substituted diazocyclopropanes and cyclopropyldiazonium ions, which can react according to 1,3-dipolar cycloaddition or azo-coupling pattern with appropriate substrates. The nature of substituents in the cyclopropyl ring have a pronounced influence on the product
    N-亚硝基-N-环丙基脲在 5-7 °C 下用含有 15-20% H2O 的 K2CO3 处理分解允许同时生成取代的重氮环丙烷和环丙基重氮离子,它们可以根据 1,3-偶极环加成或偶氮-耦合模式与适当的基板。环丙基环中取代基的性质对产物比率(并且可能对重氮化合物和重氮离子之间的平衡)有显着影响。因此,在等摩尔量的甲基丙烯酸甲酯作为重氮化合物的捕集剂和 2-萘酚作为重氮离子的捕集剂存在下用碱处理时,N-环丙基-和 N-(2,2-二甲基环丙基)- N-亚硝基脲偶氮偶联产物占主导地位。相反,N-(2,2-二氯环丙基)-N-亚硝基脲主要转化为 1, 3-环加成产物。建议对实验数据进行合理化处理。

    4′,4′-Dimethyl[16α,17α]spiropentanopregn-4-ene-3,20-dione was synthesized. The addition of diazo-2,2-dimethylcyclopropane generated from N-(2,2-dimethylcyclopropyl)-N-nitrosourea to 16,17-didehydropregnenolone acetate occurs regio-and stereospecifically to give 3β-acetoxy-1′,1′-dimethyl-20-oxopregn-5-ene-[16α,17α;7′,6′]-4′, 5′-diazaspiro[2.4]-hept-4′-ene in high yield. Its thermolysis affords a spiropentane-containing steroid, which is transformed into the target diketone. The anti position of the gem-dimethyl group in the fused spiropentane fragment is evident from the X-ray diffraction study of the final product.
