答案
![(9S,10S)-10-Acetoxy-8,8-dimethyl-2-oxo-9,10-dihydro-2H,8H-pyrano[2,3-f]chromen-9-yl (2Z)-2-methyl-2-butenoate](https://cnstatic.chemtradehub.com/structs/730/73069-27-9-834c.webp "(9S,10S)-10-Acetoxy-8,8-dimethyl-2-oxo-9,10-dihydro-2H,8H-pyrano[2,3-f]chromen-9-yl (2Z)-2-methyl-2-butenoate")
白花前胡甲素的合成通常通过多步反应完成。首先，从前胡甲素出发，通过酯化反应引入乙酰基，随后进行环化反应生成目标化合物。此过程中常用的催化剂包括硫酸和三苯基膦等，产率约为80%-90%。
