Process for the manufacture of 3-amino-substituted glycosylated bile acids

摘要

The present invention relates to a process for the preparation and manufacture of 3-amino-substituted glycosylated bile acid derivatives. Intermediates and related compounds are also disclosed. In particular, the present invention permits the conversion of cholic acid esters to the 3-amino-7,12-bis(glucosyl)cholic acid esters via an azide intermediate. Conditions for the purification and isolation of the desired product is also disclosed to provide an overall manufacturing process suitable for large-scale production.
