Benzyne-induced fragmentation of 1,3-oxathiolanes. A novel method for deprotection of carbonyl groups, preparation of phenyl vinyl sulfides, and 1,2-carbonyl transposition
A variety of 1,3-oxathiolanes undergo a benzyne-induced fragmentation leading to phenyl vinylsulfides and carbonyl compounds. The reaction developed here provides a novel method for deprotection of carbonyl compounds from 1,3-oxathiolanes, preparation of phenyl vinylsulfides, and 1,2-carbonyl transposition.
