Racemic narwedine may be resolved by means of a dynamic diastereomeric salt formation using di-p-toluoyl-D- tartaric acid. Both the 1:1 and 2:1 salts are formed in excellent yields and diastereomeric excesses. These salts are reduced in a highly diastereoselective and chemoselective manner to give (-)-galanthamine.
