Title:
METHOD FOR SYNTHESIZING DESMOPRESSIN
Document Type and Number:
WIPO Patent Application WO/2020/248372
Kind Code:
A1
Abstract:
Provided is a method for synthesizing desmopressin, the method comprising the following steps: 1) selection of a solid carrier resin; 2) synthesis of a main chain peptide resin; 3) cracking same and removing the resin and a protecting group; and 4) carrying out liquid-phase electrochemical oxidation to couple a disulfide bond in order to obtain the desmopressin. This method can avoid the specific selectivity of a reaction, can improve the utilization of a fragment peptide resin, the utilization of the main chain fragment, and the atomic utilization, thereby reducing the production cost, avoiding the use of the chemical oxidants iodine and hydrogen peroxide, so that same is more environmentally friendly and more in line with the concept of green chemistry.
