Reactions of 2-Diazo-1,3-dicarbonyl Compounds with Aromatic Thioketones (Superdipolarophiles)

摘要

Cycloaddition reactions of aliphatic diazo compounds are widely used in the synthesis of various nitrogen-containing and other heterocycles [1-3]. In these reactions, the most reactive dipoles are believed to be diazoalkanes and 2-diazo ketones, whereas cycloaddition of 2-diazo-1,3-dicarbonyl compounds to common dipolarophiles is not typical [2, 3].
