Reaction of lithiated N-Boc-thiazolidine with various aldehydes in the presence of (-)-sparteine afforded the products with up to 93% ee. The reaction was confirmed to proceed through a dynamic thermodynamic resolution pathway. Each diastereomeric alcohol could be converted to the corresponding optically active 1,2-ethanediols.
在(-)-鹰爪豆碱存在下,锂化的N-叔丁氧羰基噻唑烷与各种醛反应,得到了对映体过量率高达93%的产物。该反应被证实是通过动态热力学拆分途径进行的。每种非对映体醇都可以转化为相应的光学活性1,2-乙二醇。
