Aurachins A and B are alkaloids having 3‐hydroxyquinoline N‐oxide cores. An efficient method for the synthesis of 3‐hydroxyquinoline N‐oxides was established and is amenable to the totalsyntheses of aurachins A and B. Alkylation of 1‐(2‐nitrophenyl)butan‐2‐one with farnesyl bromide took place selectively at the benzylic position, and subsequent treatment of the alkylated product with sodium tert‐butoxide
Aurachins A和B是具有3-羟基喹啉N-氧化物核心的生物碱。建立了一种有效的合成3-羟基喹啉N-氧化物的方法,该方法适合于Aurachins A和B的全部合成.1-(2-硝基苯基)丁2-2-酮与法呢基溴的烷基化反应是选择性的。苄基位置,然后用二甲基亚砜中的叔丁醇钠对烷基化产物进行处理,得到aurachin B.使用1-(2-硝基苯基)butan-2-one与法呢醇衍生的环氧碘化物进行烷基化反应获得aurachin A.
