Chiral Thietanes and Thiethane-1, 1-dioxides—Novel Building Blocks for Liquid Crystals -
摘要:
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. H-1-NMR, C-13-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.
