3-formyl-4,5-dihydrofuran-2-carboxylate was obtained through the rearrangement of the parent ethyl 2-(4,5-dihydrofuran-3-yl)-2-oxoacetate and applied to the synthesis of a series of 7-alkoxy-2,3-dihydrofuro[2,3-d]pyridazines. Twelve pyridazines were obtained in yields of up to 70%.
通过对母体2-(4,5-二氢呋喃-3-基)-2-氧乙酸乙酯进行重排,获得了1,4-二羰基支架3-甲酰基-4,5-二氢呋喃-2-羧酸乙酯。一系列7-烷氧基-2,3-二氢呋喃[2,3- d ]哒嗪的合成。获得了十二种哒嗪,产率高达70%。
