Kinetic resolution of phosphoryl and sulfonyl esters of 1,1′-bi-2-naphthol has been achieved via the Pd-catalyzed alcoholysis of their vinyl ethers. The highest krel value reached 36.8 with substrate 3c, and (R)-3c 99.0% ee was obtained in 43% isolated yield.
1,1'-联-2-萘酚的磷酰基和磺酰基酯的动力学拆分已通过Pd催化其乙烯基醚的醇解反应实现。对于底物3c,最高k rel值达到36.8 ,并且以43%的分离产率获得99.0%ee的(R)-3c。
