• PROCESSES FOR THE PRODUCTION OF OPTICALLY ACTIVE COMPOUNDS HAVING SUBSTITUENTS AT THE 2-POSITION

  The present invention provides a process for producing an optically active compound having a thio group at the 2-position important for manufacturing medicines. An optically active compound having a hydroxyl group at the 2-position is chlorinated with inversion of the configuration at the 2-position, and the resultant optically active compound having a chlorine atom at the 2-position is reacted with a metal thiolate to introduce a thio group with inversion of the configuration at the 2-position. This process is capable of minimizing racemization and producing an optically active compound having a thio group at the 2-position at low cost in high yield. When the optically active compound having a chlorine atom at the 2-position is reacted with the metal thiolate in coexistence with water in the reaction system, the optically active compound having a thio group at the 2-position with higher optical purity can be produced in higher yield. An optically active carboxylic acid having a thio group at the 2-position is crystallized in the presence of an aliphatic hydrocarbon solvent and/or a sulfur-containing solvent to effectively remove coexistent impurities such as an optical isomer and the like, thereby producing crystals of an optically active carboxylic acid having a thio group at the 2-position with higher purity.

  本发明提供了一种生产光学活性化合物的工艺，该化合物的 2 位上有一个硫代基，这对生产药物非常重要。一种在 2 位上具有羟基的光学活性化合物在 2 位上进行反转构型的氯化处理，然后将得到的在 2 位上具有氯原子的光学活性化合物与硫代金属进行反应，在 2 位上引入反转构型的硫代基团。这种工艺能够最大限度地减少消旋化，并以低成本、高产率生产出在 2 位上具有硫代基团的光学活性化合物。当在 2 位上有一个氯原子的光学活性化合物与金属硫醇酸盐在反应体系中与水共存的情况下发生反应时，可生产出光学纯度更高的在 2 位上有一个硫代基团的光学活性化合物。在脂肪烃溶剂和/或含硫溶剂的存在下结晶 2 位具有硫代基团的光学活性羧酸，可有效去除共存的杂质（如光学异构体等），从而生产出纯度更高的 2 位具有硫代基团的光学活性羧酸晶体。
