Addition of nucleophiles including heterocycles and precursors of vicinal tricarbonyls to azetinones generates building blocks incorporating potential electrophilic centers. Oxidation of these products provides reactive carbonyl units suitably located for reaction with the β-lactam NH yielding bicyclic products of biological interest.
将亲核试剂(包括杂环和邻近的三羰基化合物的前体)加到氮杂
环丁酮中会生成包含潜在亲电中心的结构单元。这些产物的氧化提供了适合于与β-内酰胺NH反应的反应性羰基单元,从而产生了具有
生物学意义的双环产物。
