Title:
METHOD FOR PRODUCING CARBOXYLIC ACID STEROID ESTER
Document Type and Number:
Japanese Patent JP2010047502
Kind Code:
A
Abstract:
To provide a method for producing a carboxylic acid steroid ester that, even when a steroid alcohol and a carboxylic acid in an equivalent amount are subjected to an esterification reaction, gives the corresponding carboxylic acid steroid ester in a high yield.
A steroid alcohol and a carboxylic acid are subjected to esterification in the presence of ferric chloride hexahydrate. This method gives an ester of a carboxylic acid having many carbon atoms such as octanoic acid, decanoic acid, lauric acid, myristic acid, palmitic acid, stearic acid and the like and a steroid alcohol in a high yield in a short time.
