Clemeprol is an serotonin–norepinephrine reuptake inhibitor (SNRI) antidepressant and anticholinergic agent.

It is an enantiomeric mixture of R and S isomers. Both isomers show similar pharmacological activity.

Synthesis

A synthetic pathway for clemeprol is disclosed:

The Corey-Chaykovsky epoxidation between 3-chlorobenzophenone (1) and dimethylsulfoxonium methylide (Corey's reagent) , gives 2-(3-chlorophenyl)-2-phenyloxirane (2). Further reaction with boron trifluoride etherate gives m-chlorophenyl-phenylacetaldehyde, PC12549135 (3). A second Corey-Chaykovsky epoxidation gives 2-oxirane, PC12549073 (4). Quenching with dimethylamine completes the synthesis of clemeprol (5).
