Method for producing vicinal diols of compounds (especially lanosterol and cyclohexane derivatives) by reacting compounds with acids with pKa of less than or equal to 2 in the presence of one or more reagents capable of supplying hydroxy groups

摘要

The application discloses a method of producing vicinol diols from a compound. The method is characterized by the step of reacting the compound with moderately strong acid in the presence of one or more reagents capable of supplying hydroxyl groups. Specifically described is a method of producing lanosterol or an intermediate thereof. In order to remove impurities from the lanosterol the application describes a method of forming a lanosterol intermediate then separating the intermediate from the impurities and finally converting the intermediate into lanosterol.
