千金子二萜醇二乙酰苯甲酰酯(CAS号：218916-52-0)通常如何合成？
答案
![(1aR,2E,4aR,6S,7S,7aR,8R,11aS)-4a,8-Diacetoxy-1,1,3,6-tetramethyl-9-methylene-4-oxo-1a,4,4a,5,6,7,7a,8,9,10,11,11a-dodecahydro-1H-cyclopenta[a]cyclopropa[f][11]annulen-7-yl benzoate](https://cnstatic.chemtradehub.com/structs/218/218916-52-0-d13e.webp "(1aR,2E,4aR,6S,7S,7aR,8R,11aS)-4a,8-Diacetoxy-1,1,3,6-tetramethyl-9-methylene-4-oxo-1a,4,4a,5,6,7,7a,8,9,10,11,11a-dodecahydro-1H-cyclopenta[a]cyclopropa[f][11]annulen-7-yl benzoate")
千金子二萜醇二乙酰苯甲酰酯通常通过先合成千金子二萜醇，然后与乙酰氯和苯甲酰氯反应得到。合成过程中常用催化剂如三乙胺或吡啶，产物的产率较高，大约在80%左右。
