2-Substituted naptho[2,1-b]pyran-3-ones
have been synthesised by a novel one-pot method which involves
cyclocondensation of 2-hydroxy-1-naphthaldehyde with
5-methyl-1,3,4-thiadiazol-2-ylsulfanyl-,
1H-1,2,3,4-tetrazol-1-yl-, 1H-indol-3-yl-,
quinolin-8-yloxy- and 4-methylquinolin-2-yloxy-acetic acids in
the presence of DCCâDMSO using microwaves as well as
conventional heating.
通过一种新颖的一锅法合成了 2-取代的萘并[2,1-b]吡喃-3-酮,该方法涉及 2-羟基-1-萘甲醛与 5-甲基-1,3,4-噻二唑-2-基硫酸的环缩合、
1H-1,2,3,4- 四唑-1-基-、1H-吲哚-3-基-、喹啉-8-基氧基-和 4-甲基喹啉-2-基氧基-乙酸的环缩合反应。
