aza-Wittig reaction of iminophosphorane with 4-fluorophenyl isocyanate, reacted with various nucleophiles under mild conditions to give a series of 2-substituted-3-(4-fluorophenyl)-benzofuro [3,2-d] pyrimidin-4(3H)-ones in satisfactory yield. Their structures were confirmed using NMR, EI-Ms, IR, and elementary analysis, and compound was further analyzed by single-crystal. The preliminary bioassays indicated
碳二亚胺,由亚氨基磷杂环戊烷与氮杂的维蒂希反应制得 4-氟苯基异氰酸酯在温和的条件下与各种亲核试剂反应,以令人满意的产率得到一系列2-取代的-3-(4-氟苯基)-苯并呋喃[3,2-d]嘧啶-4(3H)-。使用NMR,EI-Ms,IR和元素分析确认了它们的结构,并确定了化合物用单晶进一步分析。初步的生物测定结果表明,这些化合物在50 mg / L J Heterocyclic Chem。,2010年的浓度下,对六种真菌表现出中等的杀真菌活性。
