Surprise, surprise! The total synthesis of the marine natural product pestalone (1), a highly substituted benzophenone with strong antibiotic acitivity, has provided insight into the surprising tendency of this and related molecules to undergo intramolecular Cannizzaro–Tishchenko‐type reactions. Pestalone can be readily converted into pestalachloride A, a strongly antifungal metabolite isolated from
惊喜,惊喜!海洋天然害虫单独(1)(具有强抗生素活性的高度取代的二苯甲酮)的总合成提供了对该分子及相关分子进行分子内Cannizzaro–Tishchenko型反应的惊人趋势的深入了解。通过用pH为8的氨进行简单处理,即可轻松将Pestalone转化为瘟疫杀菌素A,这是一种从内生真菌中分离出来的强抗真菌代谢产物。
