Abstract
The synthesis of chiral thietanes and chiral thiiranes from oxiranes under Mitsunobu conditions is described. One chiral thietane was oxidized to the corresponding thietane-1, 1-dioxide. 1H-NMR, 13C-NMR, IR, MS data of the new compounds are given. In connection with a mesogenic group liquid crystal behavior could be observed for the thietane and the thiirane as well.
