Structural Diversity Based on Cyclopropane Scaffolds

A practical and efficient route for the stereoselective conversion of easily accessible homoallylic alcohols to diastereomerically pure cis- and trans-disubstituted and 1,2,3-trisubstituted cyclopropanes has been developed. The diversity of structures that can be prepared and the simplicity of the overall sequence make this route ideal for extension to solid-phase synthesis techniques and ultimately combinatorial library generation.
