The synthesis of novel 1,2,3-thiadiazol derivatives containing 2H-benzo[b][1,4]oxazin-3(4H)-one moiety as one of the substituents has been reported. A combined application of H3PO4/(CF 3CO)2O mediated acylation followed by Hurd-Mori reaction has been explored to synthesize these compounds. The scope and limitation of this strategy along with the reaction mechanism of the key step is discussed.

The synthesis of novel 2H-benzo[b][1,4]oxazin-3(4H)-one derivatives has been carried out using trifluoroacetic anhydride/phosphoric acid mediated C-C bond forming reaction as a key step. This method does not require the use of environmentally harmful AlCl3 or moisture sensitive acid chloride. A number of compounds containing the benzooxazinone moiety attached to a five-membered central heterocyclic ring was synthesized and tested for their anti-cancer properties in vitro against three cell lines e.g. A549 (lung), DLD-1 (colorectal adenocarcinoma) and MV4-11 (acute myeloid leukemia). Some of them showed anti-cancer activities along with a number of reference compounds tested. Few of them showed promising anti-leukemic properties. A brief Structure-Activity-Relationship study within the series is presented. An imidazole derivative 9c containing benzene ring with a para-CF3 group at C-2 position was identified as a potent anti-leukemic agent.
