We have developed a novel one-pot reaction to generate highly substituted furan through the addition of water followed by oxidation and unusual cyclization to naphthofuran ring under the same reaction condition.
A concise and efficient synthesis of fused isoquinolines has been established by using an environmentally friendly neat approach. In this method, the electrocyclic reaction is emphasized over the typical aza-Michael addition. This green methodology allows the synthesis of various isoquinolines, including the alkaloid decumbenine B and a fluorophore that selectively detects picric acid.
通过使用环境友好的纯净方法,建立了稠合异喹啉的简洁有效的合成方法。在该方法中,电环反应比典型的氮杂迈克尔加成更重要。这种绿色方法可以合成各种异喹啉,包括生物碱 decumbenine B 和选择性检测苦味酸的荧光团。
