On treatment with trifluoroacetic anhydride, 1-methylsulfinyl-5-hepten-2-one undergoes cyclization via its Pummerer reaction product to give 3-ethenyl-2-(methylthio)cyclopentanone. This scope of the reaction for synthesis of cyclohexanone and cycloheptanone derivatives was explored.
在用三氟乙酸酐处理时,1-甲基亚磺酰基-5-庚烯-2-酮会通过其 Pummerer 反应产物发生环化反应,生成 3-乙烯基-2-(甲硫基)环戊酮。研究人员探索了该反应合成环己酮和环庚酮衍生物的范围。
