Starting from 3,4-dimethoxyhomophthalic anhydride and 6-bromohomopiperonylamine, concise and efficient syntheses of Chilean berberis products chilenine and deoxychilenine have been demonstrated via partially divergent routes by taking advantage of facile air-oxidation of homophthalimide along with intramolecular chemoselective acylation as the key steps.
以3,4-二甲氧基高邻苯二甲酸酐和6-溴高胡椒胺为起始原料,以高邻苯二甲酰亚胺的轻松空气氧化和分子内化学选择性酰化为关键步骤,通过部分不同的路线,简洁高效地合成了智利小檗产品chilenine和deoxychilenine 。
