Article abstract of DOI:10.1021/jo00076a035

Reactions of 1-(phenylsulfonyl)-2-methylene-3-bromopropane (1) with various nitroolefins have been investigated with the purpose of devising a tandem <3 + 2>-annulation leading to nitro-substituted derivatives of methylenecyclopentanes.The conjugate addit
