The synthesis of some novel 3‐carboethoxy‐4,11‐dihydro‐11‐alkyl/phenyl‐4‐oxopyrimido[1,2‐ b ][1,2,4]benzo‐thiadiazine 6,6‐dioxides ( IVa‐c ) from 3‐amino‐4‐alkyl/phenyl‐4 H ‐1,2,4‐benzothiadiazine 1,1‐dioxides ( 1a‐c ) and diethyl ethoxymethylenemalonate ( II ) is described. The compounds have been screened for their antibacterial activity.
