(-)-Herbertenediol (3) which is regarded as a biosynthetic precursor of mastigophorenes A and B has been effectively synthesized from (R)-1,2-dimethyl-2-cyclopentene carboxylic acid by applying an intramolecular Heck reaction to the construction of the quaternary carbon center, and then horseradish peroxidase-catalyzed oxidative coupling of 3 has given rise to (-)-mastigophorenes A and B. Mastigophorenes A and B have been found to exhibit significant neuroprotective activity in primary cultures of fetal rat cortical neurons. (C) 2001 Elsevier Science Ltd. All rights reserved.
(-)-Herbertenediol (3) 被认为是从 mastigophorenes A 和 B 的生物合成前体,通过使用 (R)-1,2-二甲基-2-环戊烯羧酸,并应用分子内 Heck 反应对四元碳中心进行构建,已被有效合成。随后,通过辣根过氧化物酶催化的氧化偶联反应,3 给出了 (-)-mastigophorenes A 和 B。在胎儿大鼠皮层神经元的原代培养中,mastigophorenes A 和 B 被发现对神经元具有显著的保护活性。版权 © 2001 Elsevier Science Ltd. 保留所有权利。
