Significance

DOV21947 is in clinical trials for the treatment of pain. It is a potent inhibitor of serotonin and norepinephrine reuptake transporters and it is an N-methyl-d-aspartate agonist. The Merck paper describes a careful optimization study of two key steps: (a) the selective alkylation of (S)-(+)-epi­chlorohydrin at C3 leading to A and (b) the selective cyclization of the metallated ketimine via rotamer D.
