专利号:US-12428385-B2 优先权日:2022-05-19 标 题:Composition of a lipophilic agent for solution phase synthesis of biomolecules 发明人:LI YONGFU 权利人:LI YONGFU; BROTIDE CORE LLC 摘要:Disclosed is a lipophilic agent comprising a triazine core having lipophilic groups for organic synthesis. The lipophilic agent soluble in one system of solvent(s) wherein the lipophilic agent is participated in a chemical reaction but insoluble by adding a miscible poor solvent to change solution composition after the reaction completes. The lipophilic agent facilitates process improvement wherein practical operation only involves mixing with reactants in solution followed by precipitating with change of solution composition followed by filtering to obtain the precipitated solid, simplifying the purification by isolating the desired solid. The operation is reproducible along the progress in a multi-step synthesis, allowing pure intermediates and pure product as a solid to be rapidly obtained with ease and certainty. This invention can thus accelerate research and development of pharmaceutical biomolecules, representing a tremendous step forward for boosting productivity and greening chemical industry.
