Non-stereospecific Ring Expansion Reactions of Benzothiazoline Sulfoxides

The stereochemistry of novel ring expansion of benzothiazoline sulfoxides to benzothiazines by reaction with acetic anhydride was examined.Reaction of trans-3-acetyl-2-ethyl-2-methylbenzothiazoline 1-oxide with acetic anhydride afforded 4-acetyl-3-ethylid
