英文摘要: Ethyl 4,4,4-trifluoro-3-oxobutanoate reacted with nitrostyrenes in the presence of Et3N to afford ethyl 5-(hydroxyimino)- 4-aryl-2-(trifluoromethyl)-2,5-dihydrofuran-3-carboxylates along with a small amount of ethyl 2-hydroxy-5-imino-4-aryl-2-(trifluoromethyl)- 2,5-dihydrofuran-3-carboxylates. Treatment of ethyl 5( hydroxyimino)-4-aryl-2-(trifluoromethyl)-2,5-dihydrofuran-3-carboxylates with 1.2 equivalents of TsOH in t-BuOH, afforded ethyl 2-hydroxy-5-imino-4-aryl-2-(trifluoromethyl)-2,5-dihydrofuran-3-carboxyl ates in good yields. However, ethyl 2-ethoxy or methoxy-5-oxo-4-aryl-2-(trifluoromethyl)-2,5-dihydrofuran-3-carboxylates were obtained as major products in EtOH or MeOH along with a small amount of ethyl 2-hydroxy-5-imino-4-aryl-2-(trifluoromethyl)- 2,5-dihydrofuran-3-carboxylates.
