Abstract

For the first time Baylis-Hillman adducts derived from nitroolefins have been conveniently transformed into a novel class of building blocks, 1-[(E)-3-bromo-2-nitroprop-1-enyl]arenes and 1-[(E)-3-chloro-2-nitroprop-1-enyl]arenes, in very good yields via an SN2 reaction using simple reaction conditions. Further application of these compounds has been demonstrated for the synthesis of tris[(E)-2-nitro-3-arylallyl]amines as dendrimer cores.
