A hitherto unknown reactivity of a strained four‐membered heterocycle, 1,2‐oxazetidine, is reported. When reacted with organometallic compounds, this reagent provides electrophilic oxygen with a nitrogen‐terminated two‐carbon‐atom tether. The synthetic versatility of the products obtained was demonstrated in various transformations, leading to efficient synthesis of six‐, seven‐, and eight‐membered
据报道,迄今为止,应变四元杂环1,2-氧氮杂环丁烷的反应性迄今未知。与有机金属化合物反应时,该试剂可提供带有氮封端的双碳原子束缚剂的亲电子氧。通过各种转化证明了所获得产品的合成多功能性,从而有效合成了具有重要性的六元,七元和八元杂环系统。
