摘要

Compounds of formula (II): ##STR1## wherein Y is --CH═CH-- CH.sub.2 --CH-- or ##STR2## R.sup.1 is hydrogen or C.sub.1-4 alkyl, R.sup. 2 is hydrogen or C.sub.1-6 alkyl,PPR.sup.3 is hydrogen, nitro or C.sub.1-6 alkyl and, when Y represents ##STR3## and R.sup.2 and R.sup. 3 are hydrogen, the nitro radical is in the meta- or para- position on the benzene ring.PPare novel and have antimycoplasmal activity. They may be produced by esterification of the corresponding carboxylic acid salt.
