J. Gay et G. Scherowsky, CHIRAL THIETANES AND THIETHANE-1,1-DIOXIDES - NOVEL BUILDING-BLOCKS FOR LIQUID-CRYSTALS, Synthetic communications, 25(17), 1995, pp. 2665-2672
The synthesis of chiral thietanes and chiral thiiranes from oxiranes u
nder Mitsunobu conditions is described. One chiral thietane was oxidiz
ed to the corresponding thietane-1,1-dioxide. H-1-NMR, C-13-NMR, IR, M
S data of the new compounds are given. In connection with a mesogenic
group liquid crystal behavior could be observed for the thietane and t
he thiirane as well.
