This study describes a mesoporous aluminosilicate (ASM) catalyst-induced one-step synthesis of substituted dihydroquinolines through a hydroarylation/hydroamination cascade reaction under solvent-free conditions. A sol-gel method was utilized to prepare the ASM catalyst using tetraethyl orthosilicate (TEOS) and aluminum nitrate (Al(NO₃)₃.9H₂O). The catalytic protocol, utilizing simple starting materials and a heterogeneous catalyst in a clean reaction environment, is considered an alternative and economically viable route to synthesize a wide range of 1,2-dihydroquinoline derivatives.

串联加氢芳基化-氢化胺化反应从芳族胺和炔烃中制备1,2-二氢喹啉衍生物的非均相催化和无溶剂方法

这项研究描述被取代的二氢喹啉的中孔硅铝酸盐（ASM）催化剂诱导的一步法合成通过无溶剂条件下进行hydroarylation /加氢胺化级联反应。利用溶胶-凝胶法制备了使用原硅酸四乙酯（TEOS）和硝酸铝（Al（NO ₃）₃ .9H ₂ O）的ASM催化剂。在清洁的反应环境中利用简单的起始原料和非均相催化剂的催化方案被认为是合成多种1,2-二氢喹啉衍生物的一种经济可行的替代方法。
