The construction of 2-amino-1,3-selenazole skeleton was realized via the PhICl2/KSeCN-enabled electrophilic selenocyanation of β-enaminones and β-enamino esters followed by intramolecular cyclization under basic conditions. Compared to the classical Hantzsch strategy that utilizes selenourea or its analogues as starting materials or crucial intermediates, this method might represent an alternative
2-氨基-1,3-硒唑骨架的构建是通过β-烯胺酮和β-烯胺酯的PhICl 2 /KSeCN亲电硒氰化,然后在碱性条件下进行分子内环化来实现的。与使用硒脲或其类似物作为起始材料或关键中间体的经典 Hantzsch 策略相比,该方法可能代表了通过不同途径组装 1,3-硒唑框架的替代方法。
