In the study presented herein, 4-(1H-indol-3-yl)butanoic acid (1) was sequentially transformed in the first phase into ethyl 4-(1H-indol-3-yl)butanoate (2), 4-(1H-indol-3-yl)butanohydrazide (3) and 5-[3-(1H-indol-3-yl)propyl]-1,3,4-oxadiazole-2-thiol (4) as a nucleophile.
在本研究中,4-(1H-吲哚-3-基)丁酸(1)在第一阶段依次转化为乙基4-(1H-吲哚-3-基)丁酸酯(2),4-(1H-吲哚-3-基)丁酸肼(3)和作为亲核试剂的5-[3-(1H-吲哚-3-基)丙基]-1,3,4-噁二唑-2-硫醇(4)。
