furan-2-ylidene acetates (3a-d), obtained from the furan-2,3-diones (1a-b) and methyl/ethyl (triphenylphosphoranylidene)-acetates (2a-b), were converted via the Michael type reactions with 2,3-diaminopyridine and its derivatives (4a-c) into the corresponding pyrrol-2-ylidene-acetates (5a-j) in moderate yields (45-94%). Structures of these compounds were determined by the IR, NMR, elemental analysis
由呋喃-2,3-二酮 (1a-b) 和甲基/乙基 (三苯基正膦亚基)-乙酸酯 (2a-b) 获得的呋喃-2-亚丙基乙酸酯 (3a-d) 通过迈克尔型反应转化将 2,3-二氨基吡啶及其衍生物 (4a-c) 转化为相应的 pyrrol-2-ylidene-acetates (5a-j),产率适中 (45-94%)。这些化合物的结构通过IR、NMR、元素分析和X射线衍射法确定。
