• Zn(II)-Catalyzed Addition of Aromatic/Heteroaromatic C(sp²)–H to Azoalkenes: A Polarity-Reversed Arylation of Carbonyl Compounds

  An umpolung α-(hetero)arylation strategy that involves the Michael-type reaction between electron-rich (hetero)aromatic substrates and azoalkenes is developed. The reaction proceeds under very mild conditions at room temperature and in the presence of inexpensive, nontoxic ZnCl2 catalyst to provide access to otherwise inaccessible hydrazone structures. Subsequent hydrolysis of these latter to ketones

  提出了一种涉及富电子（杂）芳族底物与偶氮烯烃之间的迈克尔型反应的α-（杂）芳基化反应策略。该反应在非常温和的条件下，在室温下，在廉价，无毒的ZnCl 2催化剂的存在下进行，以提供通向否则无法接近的结构的通道。这些后者随后水解为酮，以及其他有价值的合成转化为各种杂环支架，证明了该方案的实用性。

  Substrate-controlled reactions have been developed for the synthesis of spirocyclopropylpyrazolones and bicyclic 4,5-dihydropyrazoles from 1,2-diaza-1,3-dienes and sulfur ylides. These protocols were carried out under mild reaction conditions without any additives in generally moderate to good yields. Plausible mechanisms for the transformations were proposed.

• Divergent base-induced reactivity of cycloalkenyl-1-diazenes

  日期：2010.8

  The different base-promoted regioselectivities of the ring closure processes in the reactions between cycloalkenyl-1-diazenes and beta-ketoesters are investigated. Under the appropriate conditions it is possible to turn the synthesis towards cycloalkenyliden-pyrroles or functionalized 3-hydroxy-hydrocinnolines. The aromatization procedure of the heteroring counterpart of the 3-hydroxy-hydrocinnolines is also reported. (C) 2010 Elsevier Ltd. All rights reserved.

  Zn(II)-catalyzed divergent synthesis of functionalized polycyclic indolines through formal [3 + 2] and [4 + 2] cycloadditions of indoles with 1,2-diaza-1,3-dienes (DDs) is reported. The nature and type of substituents of substrates are found to act as a chemical switch to trigger two distinct reaction pathways and to obtain two different types of products upon the influence of the same catalyst. The mechanism of both [4 + 2] and [3 + 2] cycloadditions was investigated and fully rationalized by density functional theory (DFT) calculations.

  Easily accessible cycloalkenyl-1-diazenes and β-dicarbonyl compounds are converted in one-pot into previously unknown functionalized fused cycloalkenyliden-pyrroles of different sizes. The domino reaction proceeds through a base-catalyzed conjugate addition/cyclization/elimination sequence.
