  Diels-Alder reactions of 2-[(trialkylsilyl)oxy]pyrylium cations of 2H-pyran-2-one and 2H-1-benzopyran-2-one derivatives

  摘要：

  The reactions of 6-methyl-2H-pyran-2-one and 2H-1-benzopyran-2-one with the 2-(trialkylsilyl)oxy dienes 6a-d in the presence of tert-butyldimethylsilyl triflate gave the [4 + 2] cycloadducts 7a-c and 8a-d regio- and stereoselectively in moderate yields. The ring junction in the cycloadducts is cis. The stereochemistry of 8a-d is discussed in terms of the H-1 NMR spectra of the compounds. Similar reactions of 3-(ethoxycarbonyl)-2-pyrones and 3-(alkoxycarbonyl)coumarins with the 2-(trialkylsilyl)oxy dienes 6a-e gave the cycloadducts 14-18 in satisfactory yields. Dehydrogenation of 7c, 8b, and 8c with DDQ in refluxing toluene afforded 23-25, respectively.

• Alkylation of Ketene Silyl Acetals with Nitroolefins Mediated by Sterically Encumbered Lewis Acids

  procedures for the corresponding reaction of esters suffer from important limitations such as modest yields, lack of demonstrated generality, inconveniently low reaction temperatures, and/or the use of a large excess of one of the two reactants. In the present work, we examined the efficacy of a series of Lewis acid catalysts for the alkylation of ketene silyl acetals with nitroolefins. Previously reported

  硝基烯烃作为“（+）CC-NH（2）”和“（+）C（C = O）R”合成子的效用受到亲核试剂存在下它们容易聚合的限制。尽管已经开发出许多方法用于酮与硝基烯烃的成功烷基化，但是目前可用于酯的相应反应的方法具有重要的局限性，例如中等收率，缺乏可证明的通用性，不方便的低反应温度和/或使用。过量的两种反应物之一。在本工作中，我们研究了一系列路易斯酸催化剂对乙烯酮甲硅烷基缩醛与硝基烯烃烷基化的功效。先前报道的使用二氯化二异丙氧基钛的条件无法在令人满意的结果中使用缺少对NO（2）基团的取代基α的硝基烯烃。相比之下，使用Yamamoto率先使用的立体拥塞的Lewis酸可获得良好至优异的结果。在该反应中成功使用硝基乙烯代表了这种相对未使用的“（+）CH（2）CH（2）NH（2）”合成子的实用性的显着扩展。

  C–C coupling of alkyl and trialkylsilyl nitronates with silyl ketene acetals yields functionalized nitroso acetals. This conversion may serve as a new simple procedure to reverse the conventional reactivity of aliphatic nitro compounds. Preliminary results on the hydrogenation of nitroso acetals into amino acids derivatives, as well as TFA-catalyzed transformations of nitroso acetals, are examined to

• Oxidative Ring-Opening Reaction of Cyclopropanone Acetals with Carbonyl Compounds via Photoinduced Electron Transfer. Generation of a .beta.-Carbonyl Radical Species and Its Application to the Synthesis of .gamma.-Hydroxy Ester Derivatives
  作者：Manabu Abe、Akira Oku

  DOI：10.1021/jo00115a022

  日期：1995.5

  Photoinduced electron transfer (PET) reactions of 2-substituted or 2,2-disubstituted cyclopropanone methyl trialkylsilyl acetals 1a-e,g and 1-siloxy-2-oxabicyclo[3.1.0]hexane (1f) with carbonyl compounds 2 (benzophenone (2a), acetophenone (2b), 2-acetonaphthone (2c), 2-acetylpyridine (2d), 4-acetylbenzonitrile (2e), 2,3-butanedione (2f), and benzoyl cyanide (2g)) were examined in the presence of Mg(ClO4)(2). Carbon-carbon bond coupling products (gamma-hydroxy esters 3 or their derivative butyrolactones 4) between 1 and 2 were formed in good yields. A mechanism is proposed for the product formation which is initiated by the single electron transfer (SET) from 1 to the excited state of 2. The SET generates a transient pair of ion radicals, i.e. a ring-opened sec- or tert-beta-carbonyl radical from 1 and a ketyl radical ion from 2 stabilized by the Mg salt. This realizes a novel type of carbon-carbon bond formation at the sterically crowded beta-position of propanoates.
