A novel approach to nitro-substituted cyclopropanes and spiropentanes via oxidation of the corresponding amines with dimethyldioxirane is reported. The method is used successfully for the preparation of a series of nitrocyclopropanes as well as for the first synthesis of 1,4-dinitrospiro[2.2]pentane.

1,3‐difunctionalization of cyclopropane is an useful organic transformation. The corresponding 1,3‐difunctionalized products are synthetic synthons and building blocks in many organic syntheses. Many existing ring‐opening difunctionalization methodologies rely primarily on the use of donor−acceptor cyclopropanes, while the difunctionalization of unactivated cyclopropanes is less exploited. In this
