selenocyanation of imidazo[1,5-a]quinolines with KSeCN under metal catalyst- and chemical oxidant-free conditions. This sustainable strategy shows a broad scope and great compatibility with functional groups, and affords synthetically and biologically important selenocyanated imidazo[1,5-a]quinolines in good to excellent yields with cheap graphite and Ni plates as the electrodes. The gram-scale synthesis was also
摘要本文报道的是在无金属催化剂和化学氧化剂的条件下,用KSeCN对咪唑并[1,5-a]喹啉进行电化学硒化的第一个例子。这种可持续的策略显示了广泛的范围和与官能团的高度相容性,并提供了合成和生物学上重要的硒代氰化咪唑并[1,5-a]喹啉,并以廉价的石墨和镍板作为电极,具有良好的产率。也成功地进行了克级合成,这可能证明该电化学方案的潜在价值。
