Pyrrylphenylethanones related to cathinone and lefetamine: synthesis and pharmacological activities

Abstract

The synthesis of various pyrrylphenylethanones resembling cathinone and lefetamine is described starting from 2-chloro-1-(1-methyl-1H-pyrrol-2-yl)-2-phenylethan-1-one. Some derivatives showed good antinociceptic activity, comparable to that of morphine. The neuropsychopharmacological profile of title compounds has been also studied to explore their action on C.N.S.
