with C–N bond formation, providing an efficient and environmentally safe approach to a variety of synthetically useful cyanoalkyl-containing β-enamino ketones with outstanding selectivity and commendable functional group compatibility. Moreover, the application of microflow technique enhanced these reactions compared with the equivalent batch reaction, significantly reducing the reaction times to 5–9
已经描述了伴随杂环取代的叠氮基高烯丙醇和环酮肟酯的氰基烷基酰化的光诱导的 1,4-杂芳基从碳中心迁移到氮中心。这种简单而强大的方案将双 C-C 键裂解与 C-N 键形成相结合,为各种合成有用的含氰基烷基的β-烯氨基酮提供了一种高效且环境安全的方法,具有出色的选择性和值得称道的官能团兼容性。此外,与等效的批量反应相比,微流技术的应用增强了这些反应,将反应时间显着减少到 5-9.3 分钟,并将底物范围扩大到超过 35 种成功底物。
