Stereoselective conjugate addition of nitrogen nucleophiles to 3,3,3-trifluoro-1-nitropropene

In order to access 1,2-diamines incorporating perfluorinated groups, the Michael-like addition of nitrogen nucleophiles to 3,3,3-trifluoro-1-nitropropene has been investigated using racemic and optically pure nucleophiles such as amines, amides, oxazolidin(on)es, and thiazolidin(on)es. Complete diastereoselectivity of the addition was achieved with 4-phenylthiazolidine-2-thione.
