Abstract

A (substituted-aralkyl)heterocyclic compound of the formula I ##STR1## wherein R.sup.1 is an azido, carbamoyl, cyano, formyl, hydroxy or nitro radical, a 1-6C 1-hydroxyalkyl, alkoxy, alkylcarbamoyl, alkylthio, alkylsulphinyl or alkylsulphonyl radical, a 2-cyanoethyl radical, optionally bearing one to four 1-6C alkyl substituents, or a 2-6C alkanoyl, halogenoalkanoyl, alkanoyloxy, alkanoylamino, dialkylcarbamoyl or alkoxycarbonyl radical; R.sup.2 and R.sup.3, which may be the same or different, are each a hydrogen atom, a 1-6C alkyl, dueterioalkyl or halogenoalkyl radical, or a phenyl or phenyl(1-6C alkyl) radical, in each of which the phenyl may optionally bear one or more substituents; or R.sup.2 and R.sup.3, together with the carbon atom to which they are attached, may form a 3- to 6-membered ring; or R.sup.1 R.sup.2 R.sup.3 C- is a 1,1-dicyanoethyl or trifluoromethylsulphonyl radical; R.sup.4 is a hydrogen or halogen atom, a cyano or nitro radical or a 1-6C alkyl or halogenoalkyl radical; R.sup.5 has any of the values defined above for the group R.sup.1 R.sup.2 R.sup.3 C but is not necessarily the same as R.sup.1 R.sup.2 R.sup.3 C, or has any of the values defined above for R.su…
