A method for inducing analgesia and/or inhibiting abuse of abusive substances includes administration of d-methadone metabolites or their structural analogs. The d-methadone metabolites, EMDP and EDDP, and their structural analogs may be incorporated into a suitable pharmaceutical composition for administration to patients. The invention includes the method itself, certain structural analogs, and pharmaceutical compositions for use in accordance with the method.
Asymmetric Cyclization of <i>N</i>-Sulfonyl Alkenyl Amides Catalyzed by Iridium/Chiral Diene Complexes
Iridium/chiral diene complexes efficiently catalyzed the asymmetric cyclization of N-sulfonyl alkenyl amides to give the corresponding 2-pyrrolidone derivatives with high enantioselectivity. A mechanistic study revealed that the reaction proceeds via nucleophilic attack of the amide on the alkene moiety.
