The invention provides new oxazolidinones of formula (I), where R1, R2, R3 and R4 are independently selected from H, F and Cl; A is certain heterocycles optionally substituted; X is selected from O, S, NR8 and CR8R9; R8 and R9 having different meanings; Y is selected from O, S, SO, SO2, NO, NR11 and CR11R12; R11 and R12 having different meanings; and n is selected from 0 and 1. It also provides different processes for the preparation of such compounds. Oxazolidinones compounds of formula (I) are active against Gram-positive and some Gram-negative human and veterinary pathogens with a weak monoamine oxidase (MAO) inhibitory activity. They are useful for the treatment of bacterial infections.
