| | (R)-5,7-difluorochroman-4-ol Usage And Synthesis |
| Uses |
(R)-5,7-difluorochroman-4-ol is an important intermediate in the synthesis of tegoprazan[1].
| | Production Methods | Preparing (R)-5,7-difluorochroman-4-ol involves taking 5, 7-difluorochroman-4-one as substrate and performing asymmetric reduction reaction in the presence of ketoreductase, coenzyme and coenzyme circulating system to obtain (R)-5,7-difluorochroman-4-ol, where ketoreductase is one or combination of two or more of short-chain dehydrogenases/reductases family (SDR), medium-chain dehydrogenases/reductase (MDR) or aldo-Keto reductase (AKR)[1].
