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.
本发明提供了制作和使用手性、非气相保护有机硼酸(包括蒎烯衍生亚氨基二乙酸(PIDA)硼酸盐)的方法,以指导和实现有机分子的立体选择性合成。此外,还提供了从溶液中纯化 PIDA 硼酸盐的方法。还提供了从 PIDA 配体中对硼酸进行脱保护的方法。纯化和脱保护方法可与硼酸的偶联或其他反应方法结合使用。去保护、偶联和纯化的迭代循环可用于合成手性非外消旋化合物。这些方法适用于自动化化学合成工艺。此外,还提供了一种自动化小分子合成装置,可利用去保护、偶联和纯化的迭代循环,自动立体选择性合成手性非外消旋小分子。
