Abstract
Abstract A series of 2-heterosubstituted 1,3-oxathianes were synthesized and their reactivity toward a strong base, sec -butyllithium, was studied. It was shown that sec -butyllithium attacked 2-heterosubstituted 1,3-oxathianes in three different ways depending upon the heteroatom at C-2; the removal of the proton at C-2, the nucleophilic attack at the heteroatom, or the nucleophilic attack at C-2 took place.
