    摘要: A compound of the formula ##STR1## in which R.sup.1 and R.sup.2 taken together represent a polymethylene chain having 3 or 4 carbon atoms, or a polymethylene chain having 3 or 4 carbon atoms substituted by at least one lower alkyl radical having 1 to 4 carbon atoms, R.sup.3 is hydrogen, hydrocarbyl or substituted hydrocarbyl and X represents cyano, a group --SO.sub.3 M or a group --S--R.sup.4 where M is hydrogen or an alkali metal such as sodium and R.sup.4 is hydrocarbyl or substituted hydrocarbyl. Typically R.sup.1 and R.sup.2 complete a cyclopentene ring, R.sup.3 is alkyl such as methyl and X is a group --SO.sub.3 Na. The compounds have microbiological activity.
