Abstract
β-Amino alcohols, β-amino thiols, and β-diamines can be converted to the corresponding oxazoline, thiazoline, and imidazoline derivatives, respectively, by reaction with α,α-difluoroalkylamines under mild conditions. The reaction is applicable for the synthesis of optically active heterocyclic compounds.
Key words
α,α-difluoroalkylamine - heterocycle - amino alcohol - oxazoline - thiazoline - imidazoline
