Patent number: 7855296Abstract: Disclosed is a method of making (?)-cocaine efficient for use on a large scale. The cocaine is created by reacting an aqueous solution of (+)-2-carbomethoxytropinone (2-CMT) bitartrate, sodium amalgam and an acid that forms a highly soluble sodium salt to form (?)-methylecgonine. (?)-Methylecgonine is converted into (?)-cocaine. Sodium amalgam is continuously supplied from an electrolyzing unit to a reactor containing the aqueous solution of (+)-2-carbomethoxytropinone bitartrate and spent amalgam is continuously removed and regenerated. The aqueous solution is prepared by adding (rac)-2-CMT in chloroform to a solution of (+)-tartaric acid in water to create an aqueous phase having diastereomeric salts of 2-CMT with (+)-tartaric acid. An organic solvent is added to the aqueous phase and the crystals obtained from the combined aqueous phase and organic solvent are dried to obtain substantially pure crystalline (+)-2-carbomethoxytropinone bitartrate.Type: GrantFiled: December 16, 2005Date of Patent: December 21, 2010Assignee: Cody Laboratories, Inc.Inventor: Vladimir F.

Publication number: 20030065183Abstract: An optically active tropinonemonocarboxylic acid ester derivative useful as an intermediate for synthesis of optically active tropane derivatives was obtained by reacting succindialdehyde with an organic amine and acetonedicarboxylic acid ester to obtain a tropinonedicarboxylic acid ester derivative, and then subjecting this derivative to enzyme-catalyzed asymmetric dealkoxy-carbonylation. Since anhydroecgonine methyl ester derived from the optically active tropinone-monocarboxylic acid ester derivative by reduction and dehydration had the same direction of optical rotation as in the case of anhydroecgonine methyl ester obtained from natural cocaine, it was proved that the obtained optically active tropinonemonocarboxylic acid ester derivative had the same absolute configuration as that of natural cocaine. The yield of the optically active tropinonemonocarboxylic acid ester derivative from the asymmetric dealkoxycarbonylation was 30 to 50 mol %, and its optical purity was 70 to 97% ee.Type: ApplicationFiled: September 26, 2002Publication date: April 3, 2003Applicant: NIHON MEDI-PHYSICS CO., LTD.Inventors: Manabu Node, Soichi Nakamura, Daisaku Nakamura
