Progress on the synthetic methods of cyclopropane derivatives

The synthesis of cyclopropane derivatives is always very important. In this review,the synthetic methods of cyclopropane derivatives are discussed,including Freund reaction,Kishner cyclopropane synthesis,Kulinovich cyclopropanol synthesis,Simmons-Smith reaction, cyclopropanation via Ylides,Carbene or Grinard regeants,hydroacylation of cyclopropenes and other ways.
