Van Au, Bijan Harichian, Michael I Hill, Mikhail Raykh, Jerry J Krupa: Process of preparing N-substituted aldonamides. Lever Brothers Company Division of Conopco, Rimma Mitelman, January 31, 1995: US05386018 (15 worldwide citation)

N-substituted aldonamides are synthesized by the reaction of alkylamines and aldonolactone. Commercially available sources of aldonolactones (e.g., lactobiono-1,5-lactone) include aldonic acid (e.g., lactobionic acid). The presence of the acid leads to the formation of an ammonium salt impurity. The ...
