Route of Synthesis (ROS)

Route of Synthesis (ROS) of Polylysine CAS 25104-18-1

ConditionsYieldWith sodium hydroxide In 1,4-dioxane; water at 20℃; for 1h; pH=10 - 11;Experimental ProcedureThis synthesis is in accordance with Galbiati, B.; Ferrario, T.; Merli, V. WP 0110851(2001). A 250 mL three-necked flask was loaded consecutively with water (20 mL), 1,4-dioxane (20 mL) and L-lysine (2.1 g, 14.4 mmol). The mixture was stirred until complete dissolution. The pH was adjusted to about 10.5 by addition of 30% NaOH. Benzylchloroformate (5.2 g, 30.6 mmol) was added while maintaining the pH at about 1011 by adding at the same time 30% NaOH. At the end of the addition, the reaction was stirred at 20° C. for about 1 hour. The pH was adjusted to 5 with 37% HCl. Ethyl acetate (30 mL) was added and the pH was adjusted to 1 with 37% HCl. The mixture was stirred at room temperature for about 30 minutes, the organic layer was separated and the aqueous layer was extracted with ethyl acetate (20 mL). The combined organic layer was washed with brine (30 mL), and dried over Na2SO4. Then, the solvent was evaporated to yield a yellowish oil (6.0 g, 99%). The oil was pre-dried by azeotropic distillation with benzene.99%With sodium carbonate In diethyl ether; water at 0℃; for 5h;Experimental Procedure1.1 Step 1,1. 155 mol of Cbz-Cl was dissolved in 100 mL of diethyl ether solution,200 mL of a 10% NaCO3 aqueous solution containing 0.0645 mol of L-lysine was added dropwise,After the addition was completed, the reaction was maintained at 0 ° C for 5 hours, and the product was obtained with an appropriate amount of 10% lemonAcidified and extracted with chloroform,The reaction layer was washed with water to give a large amount of waterN, N'-bis-benzyloxycarbonyl-L-lysine,The yield is about 95%.95%With sodium carbonate In diethyl ether; water at 0℃; for 5h;Experimental Procedure1.1 Step 1Step 1, 0.322 mol of Cbz-Cl was dissolved in 100 mL of diethyl ether solution,200 mL of a 10% NaCO3 aqueous solution containing 0.055 mol of L-lysine was added dropwise,After the dropwise addition to maintain the temperature 0 reaction 5h,The resulting product was acidified with an appropriate amount of 10% citric acid and extracted with trichloromethane.The product was washed with water and evaporated to give a large amount of N, N'-bis-benzyloxycarbonyl-L-lysine,The yield is about 93%.93%

Overcoming the "Choke Points" in Semaglutide Side Chain Synthesis with Core Technologies to Enable Efficient GLP-1 Drug Manufacturing

Semaglutide, a groundbreaking product in the GLP-1 drug class, owes its extended half-life and enhanced receptor affinity largely to its unique side chain, Ste-Glu-AEEA-AEEA-OSU (CAS: 1169630-40-3) . This side chain covalently modifies the peptide backbone, significantly improving pharmacokinetics and therapeutic performance. However, its complex structure presents two critical synthetic challenges: Precise Assembly of Repetitive AEEA Units: The side chain features consecutive AEEA (aminoethoxyethoxyacetic acid) units, which require stepwise coupling via highly activated intermediates (e.g., AEEA-AEEA). Any impurities or deviations compromise downstream reaction efficiency and may trigger irreversible byproducts. Stereochemistry and Stability of Glutamic Acid (Glu): The glutamic acid component must maintain strict L-configuration, and its carboxyl groups require directional protection (e.g., OtBu) to preserve biological activity. Leveraging deep expertise in peptide chemistry a...
