Carbon-carbon and carbon-heteroatom bond-forming reactions are main interest to organic synthesis. Different types of reactions such as polar, pericyclic and radical reactions have been employed by organic chemists for the construction of carbon-carbon and carbon-heteroatom bonds. Amination is the process by which an amino group is introduced into an organic molecule. Most commonly, amination reactions involve the use of the amine as the nucleophile and the organic compound as the electrophile [1]. However, this sense of reactivity may be reversed for some electron-deficient amines, including oxaziridines, hydroxylamines, oximes and other NO substrates. Electrophilic amination [2] involving the formation of a carbon-nitrogen bond through the reaction of a nucleophilic carbanion with an electrophilic source of nitrogen [3,4]. The electrophilic α-amination of carbonyl compounds is widely used for the preparation of natural or unnatural α-amino acids and α-amino alcohols [5]. Aminating agents such as azidodicarboxylates [6], nitroso compounds or oxaziridines are typically used as electrophilic nitrogen source [7]. The addition of β-keto esters to azodicarboxylates is one of the preferred method for electrophilic amination [8,9]. Herein we present the addition of azodicarboxylates to 1,3-dicarbonyl compounds and β-keto esters in presence of the simple organic catalyst, 1,8-diazobicyclo[5.4.0]undec-7-ene (DBU). EXPERIMENTAL Melting points were recorded on a Büchi melting point apparatus and are uncorrected. NMR spectra were recorded at A Facile Synthesis of α α α α α-Hydrazino Ketones from 1,3-Dicarbonyl Compounds Using 1,8-Diazobicyclo[5.4.0]undec-7-ene (DBU) as Organic Catalyst
