metal- and oxidant-free visible light-photoinduced protocol for directfunctionalization of 2-methylquinolines has been developed. This protocol enabled the C–H functionalization of substituted 2-methylquinolines with diacetyl or ethyl pyruvate, under environmentally friendly conditions. A mechanistic investigation based on density functional theory (DFT) calculations provided details about the origins

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.
