PREPARATION METHOD OF VALIENAMINE FROM ACARBOSE AND/OR ACARBOSE DERIVATIVES USING TRIFLUOROACETIC ACID.

摘要

The present invention relates to a preparation method of valienamine from acarbose and/or acarbose derivatives using organic acid TFA(trifluoroacetic acid). By using the method of the present invention, valienamine, the core precursor of voglibose which is a VWURQJUHWDUGDQWRI.-glucosidase and which is used for the cure of diabetes, can be produced in large quantities by using selective hydrolysis from acarbose and/or acarbose derivatives using TFA.
