A novel and facile copper-catalyzed 5-endo-trig cyclization of ketoxime carboxylates for the synthesis of 2-arylpyrroles has been developed. The reaction tolerates a range of functional groups and is a practical procedure for rapid synthesis of 2-arylpyrroles in high yields under mild conditions.
已经开发了新颖且容易的铜催化的酮肟羧酸酯的5-内-trig环化反应,以合成2-芳基吡咯。该反应容许一定范围的官能团,并且是在温和条件下以高收率快速合成2-芳基吡咯的实用方法。
