Antimicrobial compounds having the formula ##STR1## wherein R.sup.1 and R.sup.2 are independently selected from the group consisting of hydrogen and C.sub.1 -to-C.sub.4 alkanoyl; R.sup.3 and R.sup.4 are selected from the group consisting of (a) R.sup.3 is hydrogen and R.sup.4 is hydroxy, (b) R.sup.3 is hydroxy and R.sup.4 is hydrogen, (c) R.sup.3 and R.sup.4 taken together are .dbd.O; or selected from the group consisting of hydrogen and hydroxy; and R.sup.5 and R.sup.6 are independently selected from the group consisting of hydrogen, bromine and chlorine, with the proviso that at least one of R.sup.5 and R.sup.6 must be bromine. Also disclosed are pharmaceutical compositions comprising such compounds, methods of treating bacterial infection by the administration thereof and a process for preparing said compounds.
