The kinetic resolution of branched and straight chain 2-phenylsulfanyl aldehydes by the Lewis acid-catalysed asymmetric anti aldol reaction followed by reduction to single enantiomers of 1,3-diols and/or acid-catalysed cyclisation with PhS migration provides a route to enantiomerically pure cyclic ethers and lactones with full stereochemical control.
分支和直链2-苯基硫醇醛的动力学分辨通过路易斯酸催化的非对称反反应后还原为1,3-二醇的单一对映体和/或酸催化的环化反应并伴随PhS迁移,为获得具有完全立体化学控制的对映体纯的环氧乙烷和乳酸酯提供了一条途径。
