The first total synthesis of phenethylamine alkaloid based natural products discolin A, B, E and bacillimidazole B is reported, which were isolated from marine sea bacteria Tenacibaculum discolor sv11 and marine sponge. Total syntheses of discolin A, B, E and bacillimidazole B are achieved in two linear steps including condensation reaction and N-alkylation reaction with an overall yield of 68%, 35%
报道了从海洋海洋细菌Tenacibaculum discolor sv11和海绵中分离得到的基于苯乙胺生物碱的天然产物discolin A、B、E和bacillimidzo B的首次全合成。通过缩合反应和N-烷基化反应两个线性步骤实现了盘菌素A、B、E和杆咪唑B的全合成,总收率分别为68%、35%、65%和32%。总共制备了 24 种类似物,产率中等至优异。所有天然产物及其类似物均经过抗菌活性筛选。最活跃的化合物对铜绿假单胞菌的IC 50为 122.1 nM 。
