  Novel indole based NNRTIs with improved potency against wild type and resistant HIV

  摘要：

  The human immunodeficiency virus (HIV) pandemic remains a significant problem, especially in developing nations where the social and economic impacts are severe. Until a cure or vaccine for the disease is found, a constant supply of new compounds to fill the drug development pipeline is a requirement, given the tendency for the virus to rapidly develop resistance to current therapies. Here we disclose our efforts to improve upon the efficacy of cyclopropyl-indole derivatives developed as NNRTIs in our laboratories. To this end, modifications to the functionality occupying the small Val179 pocket have resulted in nearly two orders of magnitude increase in potency. (C) 2014 Elsevier Ltd. All rights reserved.

  Mild and Selective Ru-Catalyzed Formylation and Fe-Catalyzed Acylation of Free (N–H) Indoles Using Anilines as the Carbonyl Source

  摘要：

  C3-selective formylation and acylation of free (N-H) indoles under mild conditions can be achieved by using Ru- and Fe-catalyzed oxidative coupling of free (N-H) indoles with anilines, respectively. Both processes are operationally simple, compatible with a variety of functional groups and generally provide the desired products in good yields. (13)C-labeling experiments unambiguously established that the carbonylic carbon in the formylation products originated from methyl group of N-methyl aniline.

• Facile Access to 3-Acylindoles through Palladium-Catalyzed Addition of Indoles to Nitriles: The One-Pot Synthesis of Indenoindolones

  The palladium‐catalyzed addition of indoles to nitriles affords 3‐acylindoles. The reaction proceeds with high selectivity, wide substrate scope, broadly available starting materials, and an operationally simple procedure. Combination with the palladium‐catalyzed intramolecular oxidative coupling of 3‐indolylarylketone gives access to indenoindolones in a one‐pot synthesis.

  A fast and green method is developed for regioselective acylation of indoles in the 3-position without the need for protection of the NH position. The method is based on Friedel-Crafts acylation using acid anhydrides. The method has been optimized, and Y(OTf)3 in catalytic amounts is found to be the best catalyst together with the commercially available ionic liquid [BMI]BF4 (1-butyl-3-methylimidazolium tetrafluoro-borate) as solvent. The reaction is completed in a very short time using monomode microwave irradiation. The catalyst can be reused up to four times without significant loss of activity. A range of substituted indoles are investigated as substrates, and thirteen new compounds have been synthesized.

  日期：——

  A facile decarboxylative acylation of N-free indoles with α-ketonates via liquid-assisted grinding was reported. The reaction requires only a catalytic amount of Cu(OAc)2·H2O in combination with O2 as the terminal oxidant to give various 3-acylindoles with high efficiency. Additionally, this new methodology was applicable to a gram-scale synthesis.
