Abstract
Abstract AMMONIUM SALTS OF 3B-(2-O-B-D-GLUCOPYRANURONSYLA-D-GLUCOPYRANURONOSYL)OXY) OLEAN-12-EN-30-OIC ACID HEREIN DESCRIBED HAVE POTENT ANTIARRHYTHMIC ACTIVITY AND THEY ARE ALSO USEFUL SWEETENING AGENTS. THESE SUBSTANCES ARE PREPARED FROM THE MONOAMMONIUM SALT OF 3B-((2-OB-D-GLUCOPYRANURONOSYL-A-D-GLUCOPYRANURONOSY)OXY) OLEAN-11-OXO-12-EN-30-OIC ACID BY CONVERSION OF THE 11OXO FUNCTION TO AN 11-METHYLENE FUNCTION. THE REDUCTION IS FOLLOWED BY REPLACEMENT OF THE CARBOXYLIC ACID HYDROGENS WITH THE AMMONIUM ION UNDER APPROPRIATE CONDITION TO PROVIDE HYDRATED AMMONIUM SALTS. ALTERNATELY, THE REDUCED MONOAMMONIUM SALT IS ACIDIFIED TO FORM THE TRIACID. THE TRIACID IS THEN MADE ANHYDROUS AND CONVERTED TO THE ANHYDROUS MONO, DI, AND TRI-AMMONIUM SALTS.
