2(5H)-呋喃酮的水相Diels-Alder反应(英文)

Diels-Alder Reaction of 2(5H)-furanones in Water Phase

研究了2(5H)-呋喃酮、5-羟基-2(5H)-呋喃酮与环戊二烯发生Diels-Alder反应,产物用FT-IR、1HNMR、MS进行了表征。该反应在水相中进行时,反应时间为0.5 h,比在有机相反应的时间大大缩短。

Diels-Alder reaction of 2 （5H）-furanone and 5-hydroxy-2 （5H）-furanone with cyclopentadiene was studied and the structure of product was characterized by FT-IR, ^1H NMR and MS. When the reaction was carried out in water phase, reaction time was 0. 5 h, which was greatly shorter than that in organic solvent.
