A compound of the formula ##STR1## or a pharmaceutically effective salt thereof in which R.sup.1 and R.sup.2 are hydrogen or lower alkyl and R.sup.3 is halogenoalkenyl or propinyl. The compounds have pharmacological effects similar to those of phenylethylamine but are free from the amphetamine effect with an excellent therapeutic index and selectivity especially with respect to inhibition of monoaminooxidase.

polysubstituted 3-acylpyrroles from readily available unsaturated ketones and N-substituted propargylated amines have been developed. An aza-Michael/alkyne carbocyclization cascade, by cooperative catalysis using pyrrolidine and a copper salt, followed by oxidation in situ gave 3-acylpyrroles, which were also transformed further to functionalized, highly substituted 3-acylpyrroles.
