A novel, one-pot ring-expansion procedure was developed using Me3S(O)I, NaH, and Sc(OTf)3. The scope and limitations were briefly examined, and a tentative mechanism was proposed. Application of the methodology to known cyclobutanone 1 provided the corresponding cyclopentanone, which was successfully advanced to (+)-carbovir and (+)-aristeromycin.
使用Me3S(O)I,NaH和Sc(OTf)3开发了一种新颖的一锅扩环程序。简要审查了范围和局限性,并提出了一种尝试性机制。将该方法应用于已知的环丁酮1可提供相应的环戊酮,该环戊酮已成功应用于(+)-carbovir和(+)-aristeromycin。
