Various new 1-fluoro-1-alkyl(or aryl)-2-substituted cyclobutanes were synthesized stereoselectively from 1-alkyl(or aryl)cyclopropyl carbinols by the ring expansion-fluorination using (iPr)2-KHF2-(HF)n·Py, and 2-hydroxymethyl-1-fluorocyclobutanes were synthesized via a new rearrangement of (1-alkyl(or aryl)cyclopropyl) ethylene oxides.
使用(i Pr)2 -KHF 2-(HF)通过扩环氟化反应从1-烷基(或芳基)环丙基甲醇立体选择性地合成了各种新的1-氟-1-烷基(或芳基)-2-取代的环丁烷。通过新的(1-烷基(或芳基)环丙基)环氧乙烷重排合成了n ·Py和2-羟甲基-1-氟环丁烷。
