The first biomimetic synthesis of methyl (8S,9R,13R,14R)-4,4,8,9,13-pentamethyl-20(10 → 9)-abeo-ent-isocopal-5(10),11(12)-dien-15-oate—a diterpenoid with the ent-verrucosin A/B skeleton has been performed by electrophilic isomerization of methyl 12α-hydroxy-ent-isocopal-13(16)-en-15-oate. The structure and stereochemistry of the synthesized compound have been established on the basis of spectroscopic
甲基的第一仿生合成(8小号,9 - [R,13 - [R,14 - [R)-4,4,8,9,13五甲基20(10-→9)-abeo- ENT -isocopal-5(10), 11(12) -二烯-15 -酸酯-A与二萜ENT -verrucosin A / B骨架已通过的甲基12α羟基电异构化进行ENT -isocopal-13(16) -烯15 -酸酯。基于光谱数据已经确定了合成化合物的结构和立体化学。
