simple, readily available propargylphosphonium salts through propargyl–allenyl isomerization. We developed an efficient synthesis for cyclopentenes, pyrroles, and thiophenes via a sequence of propargyl–allenyl isomerizations, Michael additions, and intramolecular Wittig reactions.
炔丙基phosph类物质,即反应性迈克尔受体,可以通过炔丙基-烯丙基异构化反应从简单易得的炔丙基phosph盐生成。我们通过一系列炔丙基-烯基异构化,迈克尔加成和分子内维蒂希反应开发了一种有效的环戊烯,吡咯和噻吩合成方法。
