solvent-free conditions is explained. The prepared amidoalkyl naphthols were converted to 1,3-oxazines by Vilsmeier reagent in the presence of FeCl3/SiO2 nanoparticles. This method provides a novel route to synthesis amidoalkyl naphthol and 1,3-oxazine derivatives in terms of good yields, short reaction times, and recyclable catalyst. Graphical abstract
摘要解释了在无热溶剂的条件下,在二氧化硅纳米颗粒负载的三氯化铁存在下制备酰胺基烷基萘的有效而现代的方法。在FeCl 3 / SiO 2纳米颗粒的存在下,通过Vilsmeier试剂将制备的酰胺基烷基萘酚转化为1,3-恶嗪。从产率高,反应时间短和可回收催化剂的角度来看,该方法提供了合成酰胺烷基萘酚和1,3-恶嗪衍生物的新途径。 图形概要
