摘要：

Polyfluoro-2-alkynoic acids, R(f)-C drop C-COOH (1a-c: a, R(f)=CHF2; b, R(f)=CF3; c, R(f)=CHF2CF2CF2), readily underwent an intermolecular-intramolecular Michael addition reaction with a variety of bifunctional azanucleophiles, such as RNHCH(2)CH(2)XH (R=H, Me; X=NH, S, O, NMe) and o-phenylenediamine, to give the corresponding carboxylated and/or decarboxylated 2-(polyfluoroalkyl)imidazolidine, thiazolidine, and oxazolidine derivatives in moderate to good yields.
