N-oxides are an interesting class of experimental anticancer and antibacterial agents. Analogs with 18O incorporated into the N-oxide group may offer useful mechanistic tools. We describe the use of H218OF·CH3CN in a fast, readily executed and high-yielding preparation of 1,2,4-benzotriazine 1,4-dioxides containing an 18O-label at the 4-oxide position.
杂环苯并三嗪N-氧化物是一类有趣的实验性抗癌和抗菌剂。N-氧化物基团中包含18 O的类似物可能提供有用的机理工具。我们描述了H 2 18 OF·CH 3 CN在快速,易于执行且高产的1,2,4-苯并三嗪1,4-二氧化物在4-氧化物位置包含18 O-标记的制备中的用途。
