Benzothiadiazine 1,1-dioxide derivatives are widely used because of their diverse biological activities and medicinal prospects. In this study, iodine-oxone mediated oxidative N–S bond formation reaction was described. This new and transition-metal-free approach allows for the convenient synthesis of a variety of 1,2,4-benzothiadiazine 1,1-dioxides from readily available urea derivatives under very mild conditions
苯并噻二嗪1,1-二氧化物衍生物因其多样的生物活性和药用前景而被广泛应用。在这项研究中,描述了碘氧酮介导的氧化 N-S 键形成反应。这种不含过渡金属的新方法可以在非常温和的条件下,在不使用昂贵的试剂和催化剂的情况下,从现成的尿素衍生物中方便地合成各种 1,2,4-苯并噻二嗪 1,1-二氧化物。此外,该协议允许开发具有潜在医疗应用的关键构建块库。
