ConditionsYieldWith ammonium acetate; glacial acetic acid In ethyl acetate for 6h; Reflux;Experimental ProcedureSyringaldehyde (3.07 g, 16.87 mmol), 1,2-Bis(4-Dimethylaminophenyl)-1,2-Ethanedione (5.00 g, 16.87 mmol) and NH4OAc (6.50 g,84.35 mmol) were dissolved in 150 mL glacial acetic acid, followed byrefluxing for 6 h. The reaction mixture was poured to ice-water andammonia was added to neutralize the mixture. 500 mL ethyl acetate wasadded to extract the crude product. The organic phase was dried withanhydrous MgSO4, and the solvent was removed under reduced pressure.The resulting crude product was purified via column chromatography(silica gel, pure ethyl acetate), given the pure product as a whitesolid: yield (4.5 g, 58%). 1H NMR (400 MHz, DMSO-d6): δ 12.10 (s, 1H,NH), 8.53 (s, 1H, OH), 7.28-7.41 (m, 6H, ArH), 6.70-6.72 (m, 4H, ArH),3.84 (s, 6H, OCH3), 2.91 (s, 12H, N(CH3) 2) ppm. 13C NMR (100.6 MHz,DMSO-d6): δ 148.6, 145.2, 136.1, 129.5, 128.1, 124.4, 121.8, 112.5,103.1, 56.5, 19.0.

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...
