2-aryl-3,4-bis(carbomethoxy)furans (Ilia and 5) gave the corresponding acids la and b, which with thionyl chloride in the presence of a catalytic amount of DMFA were converted to the acid dichlorides (lla and b). In the absence of DMFA, Ib formed the anhydride of 2-(p-anisyl)-3,4-bis(carboxy)furan. The diamines (IVa and b) were obtained from lla and b. With hydrazine, lla and b were converted into the cyclic
2-芳基-3,4-双(碳甲氧基)呋喃(IIIa 和 5)的衍生物得到相应的酸 la 和 b,在催化量的 DMFA 存在下,它们与亚硫酰氯一起转化为酰二氯(IIa 和b)。在不存在 DMFA 的情况下,Ib 形成 2-(对-茴香基)-3,4-双(羧基)呋喃的酸酐。二胺(IVa和b)从IIa和b获得。使用肼,IIa 和 b 被转化为环状酰肼(Va 和 b)。
