TL;DR: In this paper, a simple metal-free synthesis of 2-alkyl, 2-cycloalkyl-, 2-aryl-, and 2-heteroaryl-substituted pyridine 3,4-dicarboxylates and their N-oxides from the corresponding methyl ketones in good to excellent yield, demonstrated with 22 examples in each case, is described.
30 citations
TL;DR: In this paper, a mixture of diethyl 1-(1-(substituted)amino)-3-oxo-3-phenylprop-1-en-2-yl)hydrazine-1,2-dicarboxylates was synthesized in one pot reaction sequences with individual reactions being very clean.
19 citations
TL;DR: In this article, a three-step one-pot synthesis of various target compounds (IV, VI, (VIII), (X, (XII), and (XIV) ) is presented.

Abstract: Herein a simple, metal-free synthesis of 2-alkyl-, 2-cycloalkyl-, 2-aryl-, and 2-heteroaryl-substituted pyridine 3,4-dicarboxylates and their N-oxides from the corresponding methyl ketones in good to excellent yield, demonstrated with 22 examples in each case, is described. The method complements the current coupling reactions of 2-heterocyclic organometallic reagents.
