Regioselective cyclization of thiocarboxylic amides with bisimidoyl chlorides - Synthesis of thiadiazolidines containing a ketenacetal substructure
The reactions between bisimidoyl chlorides of oxalic acid 1 and different thioamides derived from CH-acidic methylene compounds 2, 7 as well as thiobiuretes 9-11 were investigated. The hitherto unknown cyclic keten-N,S-acetals 3 with an oxalic acid substr
