oroxoketene Cyclic S,S-Acetals Chemistry ──Reaction of α, α′ -Dioxo (ester )ketene Cyclic S,S-Acetals with Ethylenediamine
摘要
α, α′ -Dioxo (ester ) ketene cyclic S, S-acetais 2 were reacted withethyleneddriine to chrd α, α′-dioxo (ester)ketene cyclic N, N-acetals 3 Thisprocess provides a new method for the synthesis of 3 in gnd yteld under mildcondition. All products are confirmed with elementai analpeis, IR, 1H NMR and13~C NMR
