Abstract
Heterocyclisations of 1,4-bis-nucleophiles with the tetrahydroazepin-2-one 1 and gamma-butyrolactone 2 gave imidazolidine 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 F-19- and C-13-NMR data.
