摘要:A method used for synthesizing intermediates for use in the synthesis of carotenoids and carotenoid analogs, and/or carotenoid derivatives. In some embodiments, the invention includes methods for synthesizing optically active intermediates useful for the synthesis of optically active carotenoids. Synthesis of optically active carotenoids, in one embodiment, may be accomplished by forming an optically active dihydroxy intermediate from ketoisopherone. The optically active dihydroxy intermediate may be converted into optically active astaxanthin derivatives.

权利人:DU PONT; RITTER JOACHIM C
摘要:A process is provided for the synthesis of a diaminopyridine, such as 2,6-diaminopyridine and related compounds, which are used industrially as compounds and as components in the synthesis of a variety of useful materials. The synthesis proceeds by means of a chlorine-ammonia displacement in the presence of a copper source.

标题:Automated synthesis of small molecules using chiral, non-racemic boronates
发明人：BURKE MARTIN D; LI JUNQI; GILLIS ERIC P

摘要:Provided are methods for making and using chiral, non-racemic protected organoboronic acids, including pinene-derived iminodiacetic acid (PIDA) boronates, to direct and enable stereoselective synthesis of organic molecules. Also provided are methods for purifying PIDA boronates from solution. Also provided are methods for deprotection of boronic acids from their PIDA ligands. The purification and deprotection methods may be used in conjunction with methods for coupling or otherwise reacting boronic acids. Iterative cycles of deprotection, coupling, and purification can be performed to synthesize chiral, non-racemic compounds. The methods are suitable for use in an automated chemical synthesis process. Also provided is an automated small molecule synthesizer apparatus for performing automated stereoselective synthesis of chiral, non-racemic small molecules using iterative cycles of deprotection, coupling, and purification.

摘要:The present invention relates to an improved process for the synthesis of glucagon-like-peptide-1 (GLP-1) and its analogs by using combination of solid and solution phase synthesis of Fmoc protected amino acids in a sequential manner, optionally incorporating Boc protected dipeptide for unnatural amino acid in the Sequence of GLP-1, cleaving GLP-1 sequence from the resin followed by purification; attaching side-chain to the desired amino acid in the solution phase to synthesize desired GLP-1 analog, purifying it to Semaglutide. Temperature gradient is applied during initial coupling of amino acids to facilitate completion of difficult coupling reactions.

标题 :Intermediates in the synthesis of (±)-camptothecin and related compounds and synthesis thereof
发明人：CURRAN DENNIS P; LIU HUI
权利人:UNIV PITTSBURGH
摘要:The present invention provides a short, convergent total synthesis of novel intermediates in the synthesis of (±)-camptothecin and related compounds. The present synthesis scheme includes a novel 4+1 radical annulation followed by another cyclization to simultaneously assemble rings B and C of the camptothecin compound. The present invention also provides novel chemical intermediates for such 4+1 radical annulations.
