Open‐chain bis‐Reissert compounds 1 were converted to the corresponding bis‐oxazolium intermediates via acid‐catalyzed intramolecular cyclization. These oxazolium compounds exist in a variety of tautomeric structures in which the meso‐ionic form can be intercepted by reaction with dipolarophiles in a 1,3‐dipolar‐cycloaddition reaction to produce a variety of highly functionalized bis‐pyrrole esters
通过酸催化的分子内环化反应将开链双Reissert化合物1转化为相应的双恶唑鎓中间体。这些恶唑鎓化合物以各种互变异构结构存在,其中中离子形式可以通过与双极性亲和剂在1,3-偶极-环加成反应中反应而截获,从而生成各种高度官能化的双吡咯酯2。反过来,双吡咯酯可以高产率转化为相应的双吡咯四醇3。J.杂环化学.2011。
