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:Hydrodynamic cavitation-inducing inertial, non-inertial, and combination reactors are employed in the hydrothermal synthesis of graphene and its derivatives, both in solution and vapor. Various hydrodynamic cavitation reactor embodiments are revealed. Water is used to both nucleate and 'self-heal' graphene sheet growth in solution and vapor. Various methods of combustion, hydrothermal and dehydration synthesis of graphene and its derivatives are revealed. Additionally, water and ice are used as a substrate, both alone and in combination with other substrates, to grow and recover useful graphene and its derivatives.

权利人:NANOSCALE COMBINATORIAL SYNTHE
摘要:The present invention includes methods for generating combinatorial libraries on solid phase supports in which increased productivity is achieved by pooling all common steps in synthesis without using a tracking or coding system to record the synthetic history of each compound. Methods for generating combinatorial libraries in which containers with random mixtures of solid phase particles are divided and combined together in non-random ways without the exchange of particles between containers are also provided. Various products are optionally produced in multi-stage syntheses according to the invention, such as oligomers and synthetic non-repetitive organic molecules. The methods additionally relate to the identification of each library component without adding extra synthetic, physical, optical, or electronic encoding steps during library synthesis. Combinatorial synthetic systems are also provided.
