  A practical Brønsted acid promoted benzylic C–H functionalization of 2-methylazaarenes and nucleophilic addition to aldehydes was developed in good to excellent yields. A six-membered hydrogen-bonding transition state is proposed to be crucial for the reaction. Ready availability of the two starting materials, the use of acetic acid as the catalyst and the facile reaction conditions will guarantee

  Lewis-acid-catalyzed benzylic reactions of 2-methylazaarenes with aldehydes have been investigated. Series of azaarene derivatives were afforded by this reaction. 2-(Pyridin-2-yl)ethanols with common substituents were formed through the LiNTf2-promoted aldol reaction for the first time. 2-Alkenylpyridines, exclusively in the form of the E isomers, were synthesized in the presence of LiNTf2 cooperated

  日期：2014.10

  A novel protocol for acid ionic liquid promoted C(sp(3))-H bond functionalization of alkyl azaarenes and nucleophilic addition to aldehydes was developed in good to excellent yields, which provides an efficient approach for the synthesis of alkyl-substituted azaarene derivatives. It is worthwhile to note that acid ionic liquid used for this reaction can be recycled and reused six times without a significant decrease in activity. (C) 2014 Elsevier Ltd. All rights reserved.
