How is 2-Butenoic acid, 2-methyl-,(9S,10S)-9,10-dihydro-8,8-dimethyl-10-(3-methyl-1-oxobutoxy)-2-oxo-2H,8H-benzo[1,2-b:3,4-b']dipyran-9-yl ester (CAS: 78478-28-1) typically synthesized?
Answer
![2-Butenoic acid, 2-methyl-,(9S,10S)-9,10-dihydro-8,8-dimethyl-10-(3-methyl-1-oxobutoxy)-2-oxo-2H,8H-benzo[1,2-b:3,4-b']dipyran-9-yl ester, (2Z)-](https://static.chemtradehub.com/structs/784/78478-28-1-9f76.webp "2-Butenoic acid, 2-methyl-,(9S,10S)-9,10-dihydro-8,8-dimethyl-10-(3-methyl-1-oxobutoxy)-2-oxo-2H,8H-benzo[1,2-b:3,4-b']dipyran-9-yl ester, (2Z)-")
This compound can be synthesized via a multi-step process involving esterification of a 2-methyl-2-butenoic acid with a 10-(3-methyl-1-oxobutoxy)-8,8-dimethyl-9,10-dihydro-2H,8H-benzo[1,2-b:3,4-b']dipyran-9-yl alcohol. The reaction is typically catalyzed by an acid, and high selectivity and yield are achieved under optimized conditions.
