摘要:The present disclosure relates generally to the field of synthetic organic chemistry. More specifically, the disclosure is directed to a continuous flow process for synthesis of azides from alcohols and peroxides, wherein the process comprises azidation with trimethylsilyl azide and a catalyst Amberlyst-15. It is a non-hazardous, mild and controlled reaction giving good yields of azides. The azides can be further employed for synthesis of medicinally and industrially useful chemicals.

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.

标 题 :Macrocyclization reactions and intermediates and other fragments useful in the synthesis of halichondrin macrolides
发明人：FANG FRANCIS G; KIM DAE-SHIK; CHOI HYEONG-WOOK; CHASE CHARLES E
权利人:EISAI R&D MAN CO LTD
摘要:The invention provides methods for the synthesis of a halichondrin macrolides through a macrocyclization strategy. The macrocyclization strategy of the present invention involves subjecting a non-macrocyclic intermediate to a carbon-carbon bond-forming reaction (e.g., an olefination reaction (e.g., Horner-Wadsworth-Emmons olefination), catalytic Ring-Closing Olefin Metathesis, or Nozaki-Hiyama-Kishi reaction) to afford a macrocyclic macrolide. The invention also provides compounds useful as intermediates in the synthesis of a halichondrin macrolides and methods for preparing the same.
