    摘要: Antibacterial compounds are disclosed having the formula ##STR1## and pharmaceutically acceptable salts thereof, wherein R.sup.1 is --NR.sup.4 R.sup.6, where R.sup.4 and R.sup.6 are independently selected from the group consisting of hydrogen, loweralkyl and arylalkyl or, together, R.sup.4 and R.sup.6 form a nitrogen-containing heterocycle attached at the nitrogen atom; R.sup.2 is selected from the group consisting of hydrogen, --OH and, when R.sup.3 is methylene, oxygen so as to form an epoxide; and R.sup.3 is selected from the group consisting of --CH.sub.2 OH, --NR.sup.4 R.sup.6, --(CH.sub.2).sub.n NR.sup.4 R.sup.6 and, when R.sup.2 is oxygen, methylene so as to form an epoxide, where n is 1-4 and R.sup.4 and R.sup.6 are as previously defined, with the proviso that when R.sup.2 is --OH, R.sup.3 may not be --NR.sup.4 R.sup.6 ; or R.sup.2 and R.sup.3 together are.dbd.CH.sub.2. Also disclosed are processes and intermediates useful in the preparation of the above compounds, as well as compositions containing the same and methods for their use.
