Abstract: The invention is concerned with aromatase inhibiting compounds of formula I ##STR1## where R and Ro represent hydrogen or lower alkyl; or R and Ro located on adjacent carbon atoms and together when combined with the benzene ring to which they are attached form a naphthalene or tetrahydronaphthalene ring; R.sub.1 and R.sub.2 independently represent hydrogen, lower alkyl, (lower alkyl, aryl or aryl-lower alkyl)-thio, lower alkenyl, aryl, aryl-lower alkyl, C.sub.3 -C.sub.6 -cycloalkyl, or C.sub.3 -C.sub.6 -cycloalkyl-lower alkyl; or R.sub.1 and R.sub.2 combined represent lower alkylidene, mono- or di-aryl-lower alkylidene; R.sub.1 and R.sub.2 combined also represent C.sub.4 -C.sub.6 -straight chain alkylene, lower alkyl-substituted straight chain alkylene or ortho-phenylene bridged-C.sub.2 -C.sub.

Abstract: 1-(2-phenyl-3-benzofuryl)-piperazines, e.g. those of the formula ##STR1## R=H, alkyl or halo R', R"=H, alkyl, alkoxy, alkylenedioxy, alkylthio or haloR.degree.=H, alkyl or hydroxyalkyln=2 or 3acyl derivatives, quaternaries and salts thereof are anticonvulsants.

Abstract: N-(diphenylmethoxy-mono- or bicyclic-alkyleneiminoalkyl)-dicarboximides, e.g. those of the formula ##STR1## A=aliphatic or cycloaliphatic radical R,R'=H, alkyl, halogen or CF.sub.3R"=H or both are ethyleneq=2-4and salts thereof are antiallergics and antiasthmatics.
