1 Introduction Small ring size cycloalkanes such as cyclopropanes and cyclobutanes have been found as a basic structural constituent in a wide rang of natural products~([1]). In organic synthesis, their cycloalkanes also play an important role owing to their diversity of reaction.1IntroductionSmall ring size cycloalkanes such as cyclopropanes and cyclobutanes have beenfound as a basic structuralconstituent in a wide rang of natural products[1].In organic synthesis ,their cycloalkanes also pla… 相似文献
