Levopropylhexedrine (Eventin) is an adrenergic alkylamine used as an anorectic in Germany[1][2] and patented by Smith Kline & French in 1947.[3] It has also been used in the anticonvulsant preparation barbexaclone in combination with phenobarbital to offset sedation.[4][5][6] Levopropylhexedrine is the levorotatory S-enantiomer of propylhexedrine. The dextrorotatory counterpart is known as dextropropylhexedrine.


The enantiopure synthesis of levopropylhexedrine may be accomplished in a two step reaction. The first step is the Wenker synthesis of the relevant aziridine. The second step is the simple catalytic hydrogenation of the propylhexedrine-aziridine.[7]
