Chapter 4 The unclassical products——1-substituted aryl-4-ethoxycarbonyl5-dimethylaminometheneamino-1, 2, 3-triazole were prepared under Vilsmier conditions, and the reaction mechanism was also studied.

第四章报道了在Vilsmier条件下非经典产物—1-取代芳基-4-乙氧羰基-5-二甲基氨基甲叉氨基-1，2，3-三唑的合成及反应的机理进行了讨论。

Result: Eight compounds were isolated from ethanolic extract of the brown alga D.divaricata and their structures were identified as-torreyol,4β,5α-dihydroxycubenol,3-farnesyl-p-hydroxybenzioc acid,chromazonarol,fucosterol,phenyl acetylamine,4-hydroxybenzoic acid and n-hexadecanoic acid.
