该中间体在本合成路线中的序号：(IV)Isosafrole (II) was obtained by isomerization of safrole (I) under basic conditions. Ozonolysis of (II), followed by reductive decomposition of the intermediate ozonide with Zn, furnished piperonal (III). Oxidation of aldehyde (III) with methanolic iodine produced the methyl ester (IV), which was converted to the corresponding hydrazide (V) upon treatment with hydrazine in refluxing EtOH. Finally, condensation of (V) with thiophene-2-carboxaldehyde (VI) yielded the title hydrazone.
