  Direct Conversion of Indoles to 3,3-Difluoro-2-oxindoles via Electrophilic Fluorination

  摘要：

  3,3-Difluoro-2-oxindoles can be obtained directly from indoles in moderate yields via electrophilic fluorination using N-fluorobenzenesulfonimide as a mild fluorinating reagent. The presence of tell-butyl hydroperoxide during the reaction, together with additional heating after quenching the reaction with triethylamine, is beneficial to the formation of the desired product.

  General and efficient synthesis of 2,3-unsubstituted indoles catalyzed by acidic mesoporous molecular sieves

  摘要：

  A general and efficient method for the synthesis of 2,3-unsubstituted indoles has been established by the intramolecular cyclization of N-benzyl 2-anilinoacetals. Acidic mesoporous molecular sieve (MCM-41-SO3H) has shown excellent catalytic activity on this transformation, and the 2,3-unsubstituted indoles bearing 7-substituent or strong electron-withdrawing substituents also could be achieved by this protocol. Moreover, the heterogeneous catalyst, MCM-41-SO3H, could be conveniently recovered and reused without obvious loss of the catalytic activity. This work will provide an economic and environmental-benign method for the construction of various indole derivatives. (C) 2013 Elsevier Ltd. All rights reserved.

  Efficient copper-catalyzed trifluoromethylation of aromatic iodides was achieved with TMSCF3 in the presence of trimethylborate. The Lewis acid was used to anchor the in situ generated trifluoromethyl anion and suppress its rapid decomposition. Broad applicability of the new trifluoromethylating reaction was demonstrated in the functionalization of different aromatic and heteroaromatic iodides.

  A copper-catalyzed decarboxylative trifluoromethylation of (hetero)aromatic iodides has been developed. Importantly, this new copper-catalyzed reaction operates in the absence of any ligands and metal additives. The protocol shows good functional group tolerance and is compatible with heteroaromatic systems. The reaction proved scalable to a 15 mmol scale with increased yield. Finally, late-stage installation
