were used to determine the structures of two novel degradation productions of the penicillins sodium nafcillin (1) and sodium oxacillin (2). The degradation products of compounds (1) and (2) were found to possess the novel thietan-2-one structures (3)and (4), respectively. The structure of compound (4) was confirmed by chemical synthesis via two independent routes. The structure of compound (3) was confirmed
使用高场核磁共振波谱,质谱,红外光谱和紫外光谱确定青霉素纳夫西林钠(1)和奥沙西林钠(2)的两种新型降解产物的结构。发现化合物(1)和(2)的降解产物分别具有新颖的硫杂-2-酮结构(3)和(4)。化合物(4)的结构通过两条独立的路线通过化学合成来确认。通过单晶X射线晶体学确认化合物(3)的结构。
