reaction for N-substituted pyrrole synthesis using 2,5-dimethoxytetrahydrofuran with variously substituted aromatic amines has been developed (up to 89% yield). This interesting neat strategy is free from additives including co-catalysts, ligands, and acids. Relatively low cost, environmentally benign, and handy Mn(NO3)2·4H2O is employed as the catalyst under microwave conditions with a very short reaction
已经开发了第一个使用 2,5-二甲氧基四氢呋喃与各种取代的芳族胺合成 N-取代吡咯的锰催化改性 Clauson-Kaas 反应(产率高达 89%)。这种有趣的简洁策略不含添加剂,包括助催化剂、配体和酸。在微波条件下,使用成本相对较低、环境友好、方便的Mn(NO 3 ) 2 ·4H 2 O作为催化剂,反应时间非常短(20分钟)。上述品质证明了这种反应的绿色性质。
