Abstract
Interaction of thioglycolic acid with flourenone Ia and/or anthrone Ib affo rded spiro[flourene-9,2'-(1',3'-oxathiolan)]5'-one (2a) and spiro[anthracen e-9(10H), 2`-(1',3'-oxathiolan)]-5'-one (2b) respectively. Subsequent molec ular condensation of 2a,b with primary (alkyl, aryl and heterocyclic)amines , hydroxylamin hydrochloride and hydrzines gave the corresponding spiro thi azolidine and spirothiadiazinone derivatives 3a,b-6a,b respectively.
