Gracil(e): The total synthesis of gracilamine features a potentially biomimetic intramolecular [3+2] cycloaddition to assemble its two fused five‐membered rings and a debenzylation/ring‐opening reaction to obtain the aldehyde intermediate (see scheme). The success of this synthesis provides a circumstantial evidence that supports the biosynthesis pathway of gracilamine proposed previously.
Gracil(e):gracilamine的总合成具有潜在的仿生分子内[3 + 2]环加成反应,以组装其两个稠合的五元环,并进行脱苄基/开环反应以获得醛中间体(参见方案)。该合成方法的成功提供了支持先前提出的gracilamine生物合成途径的间接证据。
