Efficient and Facile Synthesis of α-Chloroenones Bearing β-Carbonates or β-Carbamates

Efficient synthesis of α-chloroenones bearing β-carbonates or β-carbamates was achieved by rhodium(II)- catalyzed reaction of cyclic diazodicarbonyl compounds with a variety of chloroformates or carbamyl chlorides in good yields. These reactions provided a useful and rapid route to β-substituted α-haloenones. KCI Citation Count: 0
