Abstract
AbstractThe reactions of enaminones with methyl sulfonyl azide providing α‐diazoketones have been realized in pure water by means of microwave irradiation. Besides the green medium and energy source, the reactions benefit additional advantages of sustainability from the totally catalyst‐ and additive‐free conditions. More significantly, the synthesis remarks the first successful application of the featured tandem [3+2] cycloaddition and subsequent ring decomposition of the in situ generated 1,2,3‐triazoline intermediate from enaminones and sulfonyl azide in the synthesis of α‐diazoketones.
