Toward the Synthesis of Benzothiazolyl Fluoroaminosulfones

Due to the importance of allylamines in organic synthesis, the synthesis of reagents as potent precursors of aminofluoroolefins is reported from functionalized benzothiazolylsulfones. The key intermediate, a fluorovinyl sulfone, was prepared and functionalized by addition of aliphatic, aromatic amines and amino acid alkyl esters through an aza-Michael addition reaction.
