ConditionsYielddiethylamine With n-butyllithium In hexane at -60℃; for 15h; Inert atmosphere; Large scale;With Dichlorosilane In hexane at -60℃; for 15h; Temperature; Inert atmosphere; Large scale;Experimental ProcedureUnder a nitrogen atmosphere, was added 5000ml of n-butyllithium in n-hexane in the reaction vessel, at a concentration of 2.5 moles per liter. Under stirring, 1000 g of diethylamine was added dropwise to the reaction kettle to control the dropping rate to prevent the temperature of the system from being kept at -60 ° C. After the dropping was completed, the temperature inside the kettle was kept at -60 And the mixture was stirred for 15 hours. Then pass into dichlorosilane 690 grams, control passed into the kettle to maintain a speed of -60 , and finally stirred at -60 after 15 hours, warmed to room temperature. Hexane solvent was distilled off at atmospheric pressure and then vacuum distilled bis (diethylamino) silane, distillation pressure 15mmHg, distillation temperature of 70 . To give product 990 g, yield (with respect to the weight of silicon molar ratio) was 91.1%.91.1%With ethylene bis(tetrahydroindenyl)titanium dichloride; 4-fluoro-benzamidoxime; zinc 2-ethylhexanoate; Dichlorosilane; copper(II) nitrate; lithium tetraphenylborate tris(1,2-dimethoxyethane) In hexane; water at 60 - 120℃; for 5h; Temperature; Reagent/catalyst; Inert atmosphere;89%With Dichlorosilane In hexane at -25℃; for 3h; Inert atmosphere;75%

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...
