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
