A convenient and simple approach for the preparation of -CF3and C2F5 substituted pyrrolines, tetrahydropyridines, tetrahydroazepine is described. Claisen condensation of N-protected cyclic amides with esters of perfluorocarboxylic acids followed by deprotection and decarboxylation in acidic media leads to the desired products. Reduction of these imines permits to obtain 5-, 6-, and 7-membered cyclic amines with - CF3and C2F5 group in good to moderate overall yields. Georg Thieme Verlag Stuttgart - New York.
