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.

A highly efficient method for the C(sp(3))-H functionalization of methyl azaarenes to alpha-oxoesters in the presence of iron(II) acetate as an inexpensive, nontoxic catalyst with moderate-to-excellent yields has been developed. This transformation represents a facile approach to medicinally important lactic acid derivatives. (C) 2014 Elsevier Ltd. All rights reserved.
