Reactions of dimethyl 3-bromo-2-oxoglutarate 2 with binucleophiles to form heterocycles proceed on two different pathways depending on the type of reactant.Thus, strong S-nucleophiles like thioureas and thiocarbohydrazide substitute initially the bromine atom and form 2-aminothiazoles 3 - 7 and the 1,3,4-thiadiazine 8.However, o-phenylendiamines reacted to form the brominated quinoxaline-2(1H)-one derivatives 9 and 10, resp.

The compounds having a 4,11-dioxo-3-oxa-8(or 7)-thia-1-azatricyclo[7,2,0,02,6 ]undecane-2-carboxylic acid skeleton as the base structure, their esters and their salts are useful antibacterial agents.
