The syntheses and reactivities of some new cyclopropane containing C₅-building blocks with composite functionalities are described. Recent applications of cyclopropylideneacetates in short syntheses of spirocyclopropane-annulated heterocycles and cyclopropane-containing biologically active compounds are demonstrated. Cyclopropylacetylenes are employed as cyclopentane annulation reagents and are particularly useful in the construction of terpenoid frameworks. 1. Introduction 2. The Initial Experiment: 1-Chloro-1-(trichlorovinyl)cyclopropanes from Olefins 3. Cyclopropylideneacetates 4. Cyclopropylacetylenes 5. Conclusion
