  • Stereochemistry and reactivity of F- and H-vinyldiazocarbonyl compounds and their phosphazines: synthesis of pyrazoles and pyridazines
    作者:Murat B. Supurgibekov、Valerija M. Zakharova、Jochim Sieler、Valerij A. Nikolaev

    tituted (F) 2-vinyl-2-diazocarbonyl compounds, having cis-relationship of functional groups (AlkO2C, CN2), do not undergo 1,5-electrocyclization, but readily take part in the tandem Staudinger–diaza-Wittig reactions to produce trifluoromethyl-substituted pyridazines, whereas their non-fluorinated analogs (H), with trans-configuration, easily cyclize to pyrazoles, but remain intact under Staudinger–diaza-Wittig
    具有官能团(AlkO 2 C,CN 2)的顺式关系的3-(三甲基)取代的(F)2-乙烯基-2-重氮羰基化合物不进行1,5-电环化,但容易参与串联Staudinger-diaza-Wittig反应生成三甲基取代的哒嗪,而它们的非化类似物(H)具有反式构型,很容易环化成吡唑,但在Staudinger-diaza-Wittig反应条件下保持完整。H-和F反应性的差异-乙烯基氮酮乙烯基重氮乙酸酯和衍生的膦嗪显然是由AlkO 2 C和CN 2基团的不同立体化学排列引起的。

    diaza-Wittig reaction) occur as a tandem process. RF-activated carbonyls are much more reactive in Wittig olefination of diazodicarbonyl and 1,3-dioxophosphazine molecules, than non-fluorinated acyl and aroyl carbonyl groups (RFCO ≫ COAlk, COAr), and as a result non-fluorinated diazodiketones and their phosphazines do not produce pyridazines under the same conditions.
    两种方法被报告用于从含有氟烷基diazodiketones制备的3,4,6-三取代的哒嗪:维悌希/施陶丁格/序列氮杂-Wittig和施陶丁格/维蒂希/二氮杂-Wittig反应。与通过初始嗪相比,在第一阶段进行维蒂希反应可提高目标哒嗪的收率。在这两种方法中,合成的最后阶段(乙烯基膦嗪的形成和随后的diaza -Wittig反应)都是串联的过程。与未化的酰基和芳酰基羰基相比,R F活化的羰基在重氮二羰基和1,3-二氧杂嗪分子的Wittig烯化反应中具有更高的反应性(R FCO≫ COAlk,COAr),因此在相同条件下,非化的重氮二酮及其膦嗪不会产生哒嗪

  • Two-Stage Synthesis of 3-(Perfluoroalkyl)-Substituted Vinyldiazocarbonyl Compounds and Their Nonfluorinated Counterparts: A Comparative Study
    作者:G. Prakash、Valerij Nikolaev、Murat Supurgibekov
    DOI:10.1055/s-0032-1318309
    日期:——
    Two approaches for the synthesis of fluorinated (F) and nonfluorinated (H) 4-(alkoxycarbonyl)-substituted cis- and trans-vinyldiazocarbonyl compounds with substituents of variable stereoelectronic nature (H, Me, Ph, CF3, OTBS) at the C-3 atom of the vinyl double bond from the relevant 1,3-dicarbonyl compounds were compared: a pathway using the Wittig reaction followed by a diazo transfer reaction was most efficient for the synthesis of the H-vinyldiazocarbonyl compounds (total yields of up to 60%), while the yields of their F-analogues under similar conditions did not exceed 16-37%. An approach via diazo transfer followed by the Wittig reaction, in contrast, is more effective for the preparation of F-vinyldiazocarbonyl compounds (total yields 37-69%). The configuration of the resulting F-and H-vinyldiazocarbonyl compounds is evidently controlled by the steric bulk of the substituent at the C-3 atom of the vinyl double bond and, in addition, depends on the specific synthetic pathway.
