ZrCl4-Mediated Regioselective Electrophilic Amination of Activated Arenes with New Alkyl Arylaminocarbonyldiazenecarboxylates: Intermolecular and Intramolecular Reactions
Substituted aminocarbonyldiazenecarboxylates reacted with 1,3-diketones or β-ketoesters under mild reaction conditions in the presence of ZrCl4 to give highly functionalized imidazolin-2-ones via the corresponding Michael adducts. Reaction of unsymmetrical precursors resulted in the formation of only one regioisomer.
