Abstract
Antimicrobial compounds of the formula ##STR1## wherein R is hydrogen, halogen or (C.sub.1 -C.sub.4)alkyl group; R.sub.1 is hydrogen or halogen; alternatively, R and R1 may be taken together with the carbons to which they are attached to form a 5- to 7-membered carbocyclic ring, said ring optionally being aromatic; R.sub.2 is hydrogen or (C.sub.1 -C.sub.3)alkyl group; and R3 is hydrogen, substituted or unsubstituted (C.sub.1 -C.sub.18)alkyl, substituted or unsubstituted (C.sub.2 -C.sub.18)alkenyl, substituted or unsubstituted (C.sub.2 -C.sub.18)alkynyl, substituted or unsubstituted (C.sub.4 -C.sub.8)cycloalkyl or cycloalkenyl, substituted or unsubstituted (C.sub.6 -C.sub.10)aryl or arylalkyl group are disclosed.
