How is (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 (CAS: 73069-27-9) typically synthesized?
Answer
![(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://static.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")
This compound is typically synthesized via a multi-step process involving acetylation of the chromenone, followed by esterification with (2Z)-2-methyl-2-butenoic acid. The synthesis involves the use of acetic anhydride and a strong acid catalyst, such as sulfuric acid, and proceeds with high selectivity and good yield.
