Cyclopenta[c]pyrrole derivatives

Claim 1

A compound having the formula ##STR28## where each of R 3 , R 4 and R 5 is hydrogen or methyl; each R 6 group is the same or different hydrogen, formyl, and lower-alkane-1,3-diol ketals thereof, phenyl-lower-alkyl, carboxy, carbo-lower-alkoxy, chloromethyl, dichloromethyl, trichloromethyl, hydroxymethyl, hydroxycyanomethyl or lower-alkyl; and R 7 is hydrogen, lower-alkyl, halo-lower-alkyl, lower-alkenyl, lower-alkynyl, lower-alkoxy-lower-alkyl, hydroxy-lower-alkyl, lower-alkylthio-lower-alkyl, cycloalkyl, cycloalkyl-lower-alkyl, phenyl, phenyl-lower-alkyl, cyano-lower-alkyl, or divalent-lower-alkylene having its valences on different carbon atoms and joining two of the 2,4,5,6-tetrahydrocyclopenta-[c]pyrrole moieties together, and wherein the phenyl or phenyl-lower-alkyl groups can be further substituted in the phenyl nucleus by a single methylenedioxy or by from one to three members of the group consisting of lower-alkyl, lower-alkoxy, halogen, hydroxy, trifluoromethyl, lower-alkanoylamino, amino, di-lower-alkylamino, carboxyl, carboxamido, carbo-lower-alkoxy, lower-alkylmercapto, lower-alkylsulfinyl, lower-alkylsulfonyl, nitro and sulfamoyl.
