A STUDY of restricted rotation in the bithienyl series, which should give valuable information about the geometric and electronic properties of such compounds, has hitherto been very difficult to undertake owing to difficulties involved in the synthesis of such compounds.

The reactions of 3H-isobenzofuran-1-thione (1) with (S)-2-methyloxirane (2) and (R)-2-phenyloxirane (6) in the presence of SiO 2 in anhydrous CH 2 Cl 2 led to two pairs of diastereoisomeric spirocyclic 1,3-oxathiolanes, i.e., 3 and 4 with a Me group at C(5'), and 7 and 8 with a Ph group at C(4'), re
