A new method for the synthesis of 2,3-dihydrofurans from readily available starting enones and pyridinium salts has been developed. This protocol can provide a novel and effective methodology for the preparation of 2,3-dihydrofurans in a stereoselective fashion. To increase the efficiency of this reaction the one-pot process was also developed, in which the pyridinium salts were generated in situ from
已经开发了一种从容易获得的起始烯酮和吡啶鎓盐合成 2,3-二氢呋喃的新方法。该协议可以为以立体选择性方式制备 2,3-二氢呋喃提供一种新颖有效的方法。为了提高该反应的效率,还开发了一锅法,其中吡啶鎓盐由相应的卤化物原位生成。
