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.

摘要:The present invention relates to the field of total chemical synthesis of ubiquitin and related peptides. More in particular, a method is provided of solid phase synthesis of ubiquitin, ubiquitin mutants and derivatives thereof. It was the object of the present invention to provide an approach for the total chemical synthesis of ubuiqitin, which allows for the chemical synthesis of virtually any Ub mutant and giving high overall efficiency and purity. The present inventors have surprisingly found that this object can be realized with a method relying on incorporation of special amino acid building blocks. This approach was found to allow for exceptionally high yields of up to 14% and to provide an synthetic entry into virtually any ubiquitin derivative.
