α-(2-Benzothiazolylthio) alkanoates were prepared by the reaction of β-keto esters with 2- (morpholinothio) benzothiazole in refluxing alcohols. Sulfenylating cleavage of α- methoxycarbonylcycloalkanones afforded the corresponding ω-alkoxycarbonyl-and/or ω- carbamoyl-α-(2-benzothiazolylthio) alkanoates.
