The reaction of cyclic thioimidates with active methylene compounds in the presence of acetic acid anhydride was studied. In case of six- and seven-membered derivatives the reaction proceeded via substitution of thiomethoxy group affording cyclic enamines. In case of five-membered derivatives the reaction proceeded via opening of the thioimidate ring affording functionalized aminopropane derivatives. (C) 2015 Elsevier Ltd. All rights reserved.
