A novel rearrangement of 2(5H)-furanones is described. When refluxed in aq. Ethanolic solution in the presence of excess KOH, the 2,5-dihydro-2-oxofuran-3-carboxamides 6 underwent a novel rearrangement to the corresponding 4,5-dihydro-4-oxo-2-(phenylamino)-3-furancarboxylic acids 1 in moderate-to-excellent yields.
描述了2 (5H)-呋喃酮的新型重排。在水溶液中回流时。在过量的KOH存在下的乙醇溶液中,2,5-二氢-2-氧呋喃-3-羧酰胺6发生了新的重排,变成了相应的4,5-二氢-4-氧-2-(苯基氨基)-3-呋喃羧酸酸1以中等至优异的产量。
