  Indol-2-yltributylstannane: A Versatile Reagent for 2-Substituted Indoles

  摘要：

  A general method for 2-substituted indoles via the palladium-catalyzed coupling of indol-2-ylstannanes is described. (N-Methylindol-2-yl)tributylstannane (1) reacts with a variety of electrophiles under very mild conditions: [N-tert-Butoxycarbonyl)indol-2-yl]tributylstannane (3) is much less reactive in the coupling reactions and reacts only with certain activated electrophiles. [N-[[(Trimethylsilyl)ethoxy]methylindol-2-yl]tributylstannane (4) behaves similarly to 1 and the removal of the [(trimethylsilyl)ethoxy]methyl group can be achieved with tetra-n-butylammonium fluoride in DMF in the presence of ethylenediamine.

  N-取代的吲哚硼酸酯的反应研究：钯催化的交叉偶联反应和分子内烷基迁移反应

  摘要：

  研究了具有各种N-保护基的吲哚硼酸酯的钯催化的交叉偶联反应，其中发现N-甲基，N-甲氧基和N-叔丁氧基羰基是有用的。但是，（1-甲氧基甲基吲哚-2-基）硼酸三乙酯不能用于该反应。还发现三（1-甲氧基甲基吲哚-2-基）硼酸烷基酯的烷基迁移反应产生2-烷基-1-甲基吲哚，伴随着1-甲氧基甲基意外地还原为1-甲基。

  Gold(I)-catalyzed cross-coupling reactions of aryldiazonium salts with organostannanes are described. This redox neutral strategy offers an efficient approach to diverse biaryls, vinyl arenes and arylacetylenes. Monitoring the reaction with NMR and ESI-MS provided strong evidence for the in situ formation of Ph3PAuIR (R = aryl, vinyl and alkynyl) species which is crucial for the activation of aryldiazonium

  heterocyclic silanols undergo cross-coupling with a variety of aromatic iodides and bromides under mild conditions. In situ deprotonation of the silanols with an equivalent amount of sodium hydride in toluene generates the sodium salt that couples with iodides under the action of Pd(2)(dba)(3).CHCl(3) in good yield at room temperature to 50 degrees C. The aromatic bromides also couple with these salts

• Palladium-Catalyzed Cross-Coupling of Five-Membered Heterocyclic Silanolates

  The preparation of pi-rich 2-aryl heterocycles by palladium-catalyzed cross-coupling of sodium heteroarylsilanolates with aryl iodides, bromides, and chlorides is described. The cross-coupling process was developed through extensive optimization of the following key variables: (1) identification of stable, isolable alkali metal silanolates, (2) identification of conditions for preformation and isolation of silanolate salts, (3) judicious choice in the palladium catalyst/ligand combination, and (4) selection of the protecting group on the nitrogen of indole. It was found that the alkali metal silanolates, either isolated or formed in situ, offered a significant rate enhancement and broader substrate scope over the use of silanols activated by Bronsted bases such as NaOt-Bu. In addition, the optimized conditions for the cross-coupling of 2-indolylsilanolates were readily applied to the cross-coupling of 2-pyrrolyl-, 2-furyl-, and 2-thienylsilanolates.
