Consecutive intramolecular desymmetrization and kinetic resolution of 2-substituted N-phenoxycarbonylserinols have been achieved in one-pot by a single chiral catalyst, bisox(7)–CuCl2, to form oxazolidinones with remarkable enantioselectivities (94–99% ee) as tert-alkylamine building blocks. The process culminates in a dual-function of the chiral catalyst.
在一锅法中,通过单一手性催化剂bisox(7)-CuCl2,实现了2-取代的N-苯氧羰基
丝氨酸醇的分子内连续非对称化和动力学拆分,生成具有出色对映选择性(94-99% ee)的
噁唑啉酮,作为叔烷基胺构建块。该过程最终实现了手性催化剂的双重功能。
