Route of Synthesis (ROS)

Route of Synthesis (ROS) of TETRAVINYLSILANE CAS 1112-55-6

ConditionsYieldWith palladium(II) acetylacetonate; potassium fluoride In N,N-dimethyl-formamide at 130℃; under 1500.15 Torr; for 3h; Reagent/catalyst; Time; Hiyama Coupling; Inert atmosphere;Experimental ProcedureGeneral procedure: A mixture of organohalides (1a-h) (0.25mmol), vinysilanes 2a (0.3mmol) or 2c (0.075mmol), potassium fluoride (0.6mmol), and supported palladium NPs catalyst (Pd/substrate ratio 1mol%) was suspended in DMF (1ml). Then, the flask was evacuated under vacuum and refilled with argon. The evacuation/refilling cycle was repeated three times (pressure 2bar). The mixture was stirred at 130°C, and the reaction was monitored by GC and GC-MS. The reaction was performed for the time required ranging from 1.5 to 24h, to obtain the maximum yield of 3a-h products.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...
