  Diverse synthesis of pyrano[2,3-b]indol and dihydropyrano[2,3-b]indol via tunable Lewis bases catalyzed domino reactions

  摘要：

  We first reported an example of diverse synthesis of pyrano[2,3-b]indol and dihydropyrano[2,3-b]indol from the same starting materials. In these domino reactions, we can control the reaction conditions to give three new products: pyrano[2,3-b]indol, dihydropyrano[2,3-b]indol with E or Z exocyclic double bond. Using DABCO as catalyst in THF, dihydropyrano[2,3-b]indol with E exocyclic double bond and pyrano[2,3-b]indol were obtained at room temperature and 65 degrees C, respectively. In contrast, when DMAP was selected as catalyst, dihydropyrano[2,3-b]indol with Z exocyclic double bond was formed in toluene at 80 degrees C. (C) 2015 Elsevier Ltd. All rights reserved.

• Condensations of Ethyl 3-Ethoxy-4-(triphenylphosphoranylidene)-2-butenoate with α,β-Unsaturated Carbonyl Compounds

    Wittig condensations of α,β-unsaturated carbonyl compounds with ethyl 3-ethoxy-4-(triphenylphosphoranylidene)-2-butenoate gave good to high yields of (2 E ,4 E ,6 E )-ethyl 3-ethoxy-2,4,6-alkatrienoates. Some of last mentioned compounds were almost quatitatively hydrolysed to (4 E ,6 E )-ethyl 3-oxo-4,6-alkadienoates. This method can therefore be used as an attractive alternative for the preparation

  α，β-不饱和羰基化合物与3-乙氧基-4-（三苯基正膦 亚基）-2-丁烯酸乙酯的Wittig 缩合得到良好的高产率的（2 E ，4 E ，6 E ）-乙基3-乙氧基-2,4 ，6-链烷酸。最后提到的一些化合物几乎被定量水解为（4 E ，6 E ）-3-氧代-4,6-链二烯酸乙酯。因此，该方法可以用作制备不饱和共轭β-酮酯的有吸引力的替代方法，该不饱和共轭β-酮酯以前是由α，β-不饱和羰基化合物和3-氧代-4-（三苯基正膦基）丁酸乙酯以极低的收率制备的。
• Functionalized cyclopentadienyl rhodium(iii) bipyridine complexes: synthesis, characterization, and catalytic application in hydrogenation of ketones

  A series of highly functionalized cyclopentadienyl rhodium(III) complexes, [Cp′Rh(bpy)Br](ClO4) (Cp′ = substituted cyclopentadienyl), was synthesized from various multi-substituted cyclopentadienes (Cp′H). [Rh(cod)Cl]2 and Cp′H were firstly converted to [Cp′Rh(cod)] complexes, which were then treated with Br2 to give the rhodium(III) dibromides [Cp′RhBr2]2. The novel complexes [Cp′Rh(bpy)Br](ClO4) were obtained readily by the reaction of 2,2′-bipyridine with [Cp′RhBr2]2. These rhodium complexes [Cp′Rh(bpy)Br](ClO4) were fully characterized and utilized in the hydrogenation of cyclohexanone and acetophenone with generally high yields, but they did not exhibit the same reactivity trends for the two substrate ketones. The different activity of these complexes for the different substrates may be due to the influence of the substituents on the Cp′ rings.

  以多种多取代环戊二烯（Cp′H）为原料，合成了一系列高功能化环戊二烯铑（III）络合物[Cp′Rh(mby)Br](ClO4)（Cp′=取代环戊二烯基）。首先将[Rh(cod)Cl]2 和 Cp′H 转化为[Cp′Rh(cod)]配合物，然后用 Br2 处理，得到铑（III）二溴化物[Cp′RhBr2]2。2,2′-联吡啶与[Cp′RhBr2]2反应，很容易得到新型络合物[Cp′Rh(bpy)Br]( )。这些铑络合物[Cp′Rh(bpy)Br]( )得到了充分表征，并被用于环己酮和苯乙酮的氢化反应，产量普遍较高，但它们对两种底物酮的反应趋势并不相同。这些配合物对不同底物的不同活性可能是由于 Cp′环上取代基的影响。

  4-Alkenylfulvenes were prepared by the annulation of 1,4-ynediones and allylidenetriphenylphosphorane and subjected to a thermal reaction. Highly regio- and stereoselective [4+2] cycloaddition is accomplished with 4-((R)-3-benzyloxypent-4-en-1-yl)fulvene and the resulting adduct is transformed into bicyclo[3.3.0]octene derivative.
