Abstract

Abstract Heterocyclisations of 1, 4-bis-nucleophiles with the tetrahydroazepin-2-one 1 and γ- butyrolactone 2 gave imidazoline 9, 12, oxazolidines 3, 10, 13, 15 and thiazolidine 4 as a mixture of two diastereoisomers in various proportions. The structure and the relative configurations of these heterocycles were established by X-ray diffraction analysis and by comparison of 19 F-and 13 C-NMR data.
