The preparation and characterization of new analogues of the imidazoline insulin secretagogue efaroxan 1 are described. These include 1,2,4-triazole, 1,3,4-oxadiazole, pyrimidine, 1,4,5,6-tetrahydropyrimidine and 1,2-dihydro-1,2,4,5-tetrazine analogues. Bromination of 2,3-dihydro-2-ethylbenzo[b]furan-2-carbonitrile 19 gives the 3,3-dibromo analogue 28, which is readily hydrolysed to the corresponding
描述了咪唑啉胰岛素促分泌剂依法洛辛1的新类似物的制备和表征。这些包括1,2,4-三唑,1,3,4-恶二唑,嘧啶,1,4,5,6-四氢嘧啶和1,2-二氢-1,2,4,5-四嗪类似物。2,3-二氢-2-乙基苯并[ b ]呋喃-2-腈19的溴化得到3,3-二溴类似物28,其易于水解为相应的酮29。还原该酮得到醇31,为非对映异构体的混合物,其使用三氟化二乙基氨基硫将其转化为氟化物32。
