    (ω-Ammonioalkyl)cyclopentadienides by Rhodium-Catalyzed Vinylcarbene Transfer to Semicyclic Enaminocarbonyl Compounds
    摘要:
    The rhodium(ll) catalyzed reaction of vinyldiazoacetate 2 with semicyclic beta-enaminocarbonyl compounds 1 provides (omega-(methylammonio)-alkyl)cyclopentadienides 3. This transformation represents a novel reaction cascade which combines carbenoid addition at a C=C bond with ring chain transformation. In some cases, products resulting from vinylcarbene insertion into the enaminic C-H bond of 1 are also isolated, These dienamines undergo subsequent isomerization to furnish betaines 3.

  • Synthesis of Pyridines by Carbenoid-Mediated Ring Opening of 2<i>H</i>-Azirines
    作者:Nicole S. Y. Loy、Alok Singh、Xianxiu Xu、Cheol-Min Park
    DOI:10.1002/anie.201209301
    日期:2013.2.18
    a wide range of substituents on the resulting pyridine ring using mild reaction conditions (see scheme; esp=α,α,α′,α′‐tetramethyl‐1,3‐benzenedipropionic acid). The formation of the key intermediate is catalyst‐controlled, and subsequent cyclization and oxidation affords pyridines in excellent yields. The method has been used for the efficient synthesis of polyarylpyridines.

  • A ‘sulfonyl-azide-free’ (SAFE) aqueous-phase diazo transfer reaction for parallel and diversity-oriented synthesis

    Diazo transfer reactions are notoriously associated with the use of potentially explosive sulfonyl azides. The first ‘sulfonyl-azide-free’ (SAFE) protocol for producing diazo compounds from their active-methylene precursors via the Regitz diazo transfer reaction was developed and has displayed a remarkable substrate scope. It can be applied to generating arrays of diazo compounds for further evolution
    众所周知,重氮转移反应与潜在爆炸性磺酰叠氮化物的使用有关。研发了第一个通过Regitz重氮转移反应从其活性亚甲基前体生产重氮化合物的“无磺酰叠氮”(SAFE)方案,该方案已显示出显着的底物范围。它可用于产生重氮化合物的阵列,以通过组合化学和一系列支架产生的转化进一步进化。
  • Some New Derivatives of 2-Pentenedioic Acid
    作者:Vladimír Tolman、Petr Sedmera
    DOI:10.1135/cccc19931430
    日期:——

    Michael addition of N-acylaminomalonates to propynoic esters led to the (E)-4-acylamino)-4-carboxy-2-pentenedioic triesters IIa - IIf. On deprotection and decarboxylation, these compounds afforded 2-(N-acylamino)-2-pentenedioic acid derivatives IIIa - IIIc. Dimethyl (E)-4-diazo-2-pentenedioate (IV) was prepared by direct transfer of the diazo group. On treatment of IV with 4-toluenesulfonic acid, 2-(4-toluenesulfonyloxy)-2-pentenedioate (V) was formed. Iodination of (E)-2-pentenedioic acid led directly to the 2,4-diododerivative VII. From dimethyl (E)-4-oxo-2-pentenedioate the oximino ester VIIIa and the free oximino acid VIIIb were prepared.

    N-酰胺马隆酸酯与丙炔酸酯的Michael加成反应导致了(E)-4-酰胺-4-羧基-2-戊二酸三酯IIa - IIf。去保护和脱羧后,这些化合物生成了2-(N-酰胺基)-2-戊二酸生物IIIa - IIIc。通过直接转移重氮基团制备了二甲基(E)-4-重氮基-2-戊二酸酯IV。将IV与对甲苯磺酸处理后,生成了2-(对甲苯磺酸氧基)-2-戊二酸酯V。对(E)-2-戊二酸化直接导致了2,4-二生物VII。从二甲基(E)-4-氧基-2-戊二酸酯制备了氧胺酯VIIIa和游离氧胺酸VIIIb。
  • One-Pot Synthesis of Highly Functionalized Pyridines via a Rhodium Carbenoid Induced Ring Expansion of Isoxazoles
    作者:James R. Manning、Huw M. L. Davies
    DOI:10.1021/ja803139k
    日期:2008.7.1
    A concise one-pot synthesis of highly functionalized pyridines has been developed. The first step in the reaction sequence is the formal insertion of rhodium vinylcarbenoids across the N-O bond of isoxazoles. Upon heating, the insertion products undergo a rearrangement to give 1,4-dihydropyridines. DDQ oxidation then affords the corresponding pyridines in 31-84% yield. The process has proven general
    已开发出高度官能化吡啶的简洁一锅法合成。反应序列中的第一步是将乙烯基卡宾正式插入到异恶唑的 NO 键上。加热后,插入产物发生重排,得到 1,4-二氢吡啶。然后DDQ氧化以31-84%的产率提供相应的吡啶。该过程已被证明适用于一系列类卡宾和异恶唑组分,并代表了合成功能化吡啶的独特断开策略。
  • 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
    DOI:10.1016/j.tetlet.2010.11.073
    日期:2011.1
    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。
