  由氟化重氮二酮合成4-氟烷基取代的哒嗪

  摘要：

  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。与通过初始磷嗪相比，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。与未氟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1,3-二氧杂磷嗪分子的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，非氟化的重氮二酮及其膦嗪不会产生哒嗪。

  Reaction of (alkyloxycarbonyl)- and (benzoyl)-methyl­enetriphenylphosphoranes with fluorine-containing diazodiketones leads to olefination of the perfluoroacyl carbonyl group and formation of fluorinated vinyldiazoketones. The analogous reaction with non-fluorinated diazodiketones does not proceed under the same conditions. The resulting fluorine-containing vinyldiazoketones have an E-configuration regardless of the nature and size of the substituents.

  Fluorinated benzofuro[2,3-b]pyridines, benzo­thieno[2,3-b]pyridines and 9H-pyrido[2,3-b]indoles (α-carbolines) were synthesized via regiospecific pyridine core annulation of a number of fluoro-containing 1,3-CCC-dielectrophiles to benzofuran-2-amine, benzothiophen-2-amine and 1H-indol-2-amine. Based on the 2,4-bis(trifluoromethyl)-9H-pyrido[2,3-b]indole thus synthesized, the preparative approach towards a set of nucleosides and nucleoside mimetics bearing the α-carboline framework was elaborated.

  diketones in the presence of isothiazole-3(2H)-one 1,1-dioxides offers a chemoselective and useful tool for O-functionalization of their CO groups by interaction with transient fluorine-containing RhII-diketocarbenoids. The resulting O-alkylimidates of isothiazole 1,1-dioxides, bearing (trifluoromethyl)acetyl groups, easily react with traces of H2O giving rise to stable hydrates of the perfluoroacetyl

  在异噻唑-3（2 H）-1存在下，铑（II）催化的氟化重氮二酮的分解为1,1-二氧化物提供了一种化学选择性和有用的工具，可通过与瞬态含氟化合物相互作用来对其CO基进行O-官能化Rh II-二酮类化合物。所得的带有（三氟甲基）乙酰基的异噻唑1，1-二氧化物的O-烷基亚氨酸酯容易与痕量的H 2 O反应，产生稳定的全氟乙酰基水合物。没有ø Ñ的异构化ø -alkylimidates（类似于兰德-查普曼重排）研究了反应条件下进行了观察。
• Two-Stage Synthesis of 3-(Perfluoroalkyl)-Substituted Vinyldiazocarbonyl Compounds and Their Nonfluorinated Counterparts: A Comparative Study
  作者：G. Prakash、Valerij Nikolaev、Murat Supurgibekov

  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.
