of racemic and branched monosubstituted allylic acetates by a ruthenium-catalyzed regioselective allylic etherification. The reaction was effectively catalyzed by the chiral ruthenium catalyst, which was generated by [RuCl2(p-cymene)]2 and (S,S)-iPr-pybox and a catalytic amount of TFA, and both the allylic etherification product and recovered allylic acetate were obtained as an enantiomerically enriched
我们证明了钌催化的区域选择性烯丙基醚化的外消旋和支链单取代的烯丙基乙酸酯的动力学拆分。通过[RuCl 2(p- cymene)] 2和(S,S)-iPr-pybox以及催化量的TFA生成的手性钌催化剂有效地催化了该反应,并同时回收了烯丙基醚化产物获得对映体富集形式的乙酸烯丙酯,其值最高为103 s。
