A SnCl4.5H2O-mediated facile and efficient one-step synthesis of the tricyclic core of martinellic acid from readily available 2-(cyanomethyl)-3-oxo-N-arylbutanamides was developed and a mechanism involving consecutive hydrolysis of a cyano group and a double annulation process is proposed.
开发了一种由四氯化锡五水合物介导的、简便高效的一步法,可从容易获得的2-(氰基甲基)-3-氧代-N-芳基丁酰胺合成马丁内利酸的三环核心,并提出了一种涉及氰基连续水解和双环化过程的机制。
