  Rh(III)-Catalyzed [3 + 2] Spirocyclization of 2H-Imidazoles with 1,3-Diynes for the Synthesis of Spiro-[imidazole-indene] Derivatives

  摘要：

  An effective strategy to synthesize spirocyclic compounds, [imidazole-4,1'-indene], has been efficaciously developed relied on Rh(III)-catalyzed [3 + 2] spirocyclization of 2H-imidazoles and 1,3-diynes with excellent chemselectivity and regioselectivity. This protocol shows a straightforward way to construct the versatile spirocyclic compounds with wide functional group compatibility, high atom economy, and diverse functionalization of products.

  摘要：

  发现在烯丙基溴的存在下，苯甲酰基化合物如苯甲酰基甲酸酯衍生物与2-（对茴香基）-1，3-二甲基苯并咪唑啉之间的光反应产生了各种烯丙基化的醇。在苯甲酰基甲酸酯的反应中，建议通过苯并咪唑啉向光激发的苯甲酰基甲酸酯的电子转移，作为中间体生成α-羟基酯烯酸酯，其在苯甲酰基的羰基碳上带有负电荷。这些物质与烯丙基溴反应生成α-烯丙基-α-羟基酯。

• One-Pot Synthesis of Unsymmetrical Ketones by the Reaction of Decacarbonyldimanganese with Two Kinds of Alkyllithiums
  作者：Hiroshi M. Yamamoto、Hidehiro Sakurai、Koichi Narasaka

  DOI：10.1246/bcsj.69.157

  日期：1996.1

  Decacarbonyldimanganese (Mn2(CO)10) is utilized as a phosgene equivalent for the one-pot preparation of unsymmetrical ketones. By a successive treatment of Mn2(CO)10 with two kinds of alkyllithiums, unsymmetrical ketones are obtained in high selectivity. Unsymmetrical α-diketones are generated when the above reaction is carried out in the presence of trimethyl phosphite and is quenched with N-bromosuccinimide

• A Simple and Improved Procedure for the Conversion of Alkynes to 1,2-Diketones by Indirect Electrooxidation With Ruthenium Tetroxide as a Mediator
  作者：Sigeru Torii、Tsutomu Inokuchi、Youzou Hirata

  DOI：10.1055/s-1987-27950

  日期：——

  Indirect electrooxidation of alkynes 1 using ruthenium tetroxide as a mediator, leading to 1,2-diones 2 in 72-87%, is described. The electrolysis is carried out in the presence of a catalytic amount of ruthenium dioxide dihydrate in a two phase system of saturated aqueous sodium chloride and carbon tetrachloride. The overoxidation of 1,2-diones to the corresponding carboxylic acid, an unavoidable drawback generally encountered in the metal oxidation of acetylenes, is suppressed greatly by maintaining the pH of the aqueous phase at 4 and conducting the reaction at 0-5°C. The synthetic utility of this electrochemical oxidation is exemplified by the preparation of 2i (82%), a key intermediate for the synthesis of furaneol 4, from the commercially available 1i.

  使用四氧化钌作为介质，对炔烃1进行间接电氧化，以72-87%的产率得到1,2-二酮2。电解在含有催化量二氧化钌二水合物的水和四氯化碳两相体系中进行，使用饱和氯化钠水溶液。通过将水相的pH维持在4，并在0-5°C下进行反应，可以大大抑制1,2-二酮过氧化成相应的羧酸，这是通常在金属氧化炔烃中遇到的一个不可避免的缺点。这种方法的合成实用性通过从市售的1i制备关键中间体2i（产率82%）来证明，2i是合成furaneol 4的重要中间体。

  A catalyst-free and transition-metal-free method for the synthesis of 1,2-diketones from aerobic alkyne oxidation was reported. The oxidation of various internal alkynes, especially more challenging aryl-alkyl acetylenes, proceeded smoothly with inexpensive, easily handled, and commercially available potassium persulfate and an ambient air balloon, achieving the corresponding 1,2-diketones with up
