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.[1][2]
Synthesis
[edit]A synthetic pathway for clemeprol is disclosed: [3][4][5][6][7]
The Corey-Chaykovsky epoxidation between 3-chlorobenzophenone [1016-78-0] (1) and dimethylsulfoxonium methylide (Corey's reagent) [5367-24-8], gives 2-(3-chlorophenyl)-2-phenyloxirane [71827-53-7] (2). Further reaction with boron trifluoride etherate [109-63-7] gives m-chlorophenyl-phenylacetaldehyde, PC12549135 (3). A second Corey-Chaykovsky epoxidation gives 2-[(3-chlorophenyl)-phenylmethyl]oxirane, PC12549073 (4). Quenching with dimethylamine completes the synthesis of clemeprol (5).
