1-(2-Phenylethyl)pyrrolidine (PEP) is a chemical compound. It is an analogue of 2-phenylethylamine where the amine has been replaced by a pyrrolidine ring. The β-keto derivative is phenacylpyrrolidine and the α-methyl and β-keto (i.e., cathinone) derivative is α-pyrrolidinopropiophenone (α-PPP).
PEP is the base chemical structure for a series of stimulant drugs, including:
All of these compounds differ from PEP in that the alpha carbon is extended and a ketone is attached to the beta carbon (with the exception of prolintane), among other modifications.
