Abstract
Potassium carbonate mediated methanolysis of optically active 1,3-oxat
hiolane-2-thiones (5-membered cyclic xanthates) took place under very
mild conditions to give optically pure 1,2-episulfides. Also, methanol
ysis of ethanesulfonyloxy)alkyl]-1,3-oxathiolane-2-thiones and 2,4-dia
lkyl substituted 1,3-oxathiolane-2-thione gave 2,3-episulfides, stereo
specifically.
