and efficient method for the selective synthesis of (E)-3-amino-2-thiocyanato-α,β-unsaturated carbonyl compounds is described through a given protocol. The present approach features the use of inexpensive ammonium thiocyanate to achieve dual functionalization of 1,3-dicarbonyl compounds using TBHP as an oxidant, providing a rapid and practical route to the selective formation of both C–N and C–S bonds
通过给定的方案描述了一种直接电合成/无光催化剂、原子经济且有效的选择性合成( E )-3-氨基-2-硫氰酸根-α,β-不饱和羰基化合物的方法。本方法的特点是使用廉价的硫氰酸铵,以 TBHP 作为氧化剂实现 1,3-二羰基化合物的双官能化,为通过自由基选择性形成 C-N 和 C-S 键提供了快速实用的途径过程。该方法提供了广泛的底物范围和优异的产率,并允许进一步探索产物以构建杂环化合物和其他功能。
