Alkyl phenyl 2,3-epoxycarboxylates from the well-known Darzens glycidic esters synthesis react under very mild conditions with pyridinium-poly-hydrogen fluoride to give corresponding 3-fluoro 3-phenyllactates in almost quantitative yields with a high regio and stereoselectivity.
来自众所周知的Darzens缩水甘油酯合成的烷基苯基2,3-环氧羧酸盐在非常温和的条件下与吡啶鎓-多氟化氢反应,以几乎定量的产率以高的区域和立体选择性得到相应的3-氟3-苯基乳酸。
