专利号:US-9388131-B2 优先权日:2011-04-27 标题:Automated synthesis of small molecules using chiral, non-racemic boronates 发明人:BURKE MARTIN D; LI JUNQI; GILLIS ERIC P 权利人:UNIV ILLINOIS 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.

专利号:US-6118022-A 优先权日:1998-09-08 标 题 :Synthesis of phosphonomethyliminodiacetic acid with reduced effluent 发明人:CULLEN BARRY A 权利人:HAMPSHIRE CHEMICAL CORP 摘要:A process for the preparation of phosphonomethylglycine in high yields is disclosed. In accordance with the process of the present invention, alkali metal IDA, such as disodium IDA, is reacted with a strong mineral acid, such as HCl, to convert the salt of IDA to IDA. The IDA is then converted to soluble IDA phosphite salt by the addition of phosphorous acid, and the alkali metal salt of the strong acid is precipitated. The phosphite salt of IDA is phosphonomethylated, such as by the addition of PCl3 and formaldehyde. Optionally, phosphorous trichloride can be hydrolyzed to provide the phosphorous acid source for phosphonomethylation of the phosphite salt.
