METHOD FOR PURIFYING HIGH-PURITY BETULONIC ACID, METHOD FOR PREPARING PIPERAZINE BETULONIC ACID AMIDE DERIVATIVE USING HIGH-PURITY BETULONIC ACID AND DERIVATIVE THEREOF, AND METHOD FOR PURIFYING HIGH-PURITY BOC-LYSINATED BETULONIC ACID USING HIGH-PURITY BETULONIC ACID

摘要

The present invention relates to a method for purifying high-purity betulonic acid, a method for preparing a piperazine betulonic acid amide derivative using high-purity betulonic acid and a derivative thereof, and a method for purifying high-purity Boc-lysinated betulonic acid using high-purity betulonic acid. The present invention relates to a method for purifying high-purity betulonic acid from a product of an organic synthetic reaction between betulin extracted from the bark of a birch and a Jones oxidation reagent, synthesis of piperazine betulonic acid amide derivative using the same, utilization thereof as an antibacterial drug, purification of high-purity Boc-lysinated betulonic acid monomer ester from a product of an organic synthetic reaction between high-purity betulonic acid and lysine, and purification of high-purity Boc-lysinated betulonic acid from a product of hydrolysis of the Boc-lysinated betulonic acid monomer ester.
