The preparation and degradation of some propionylated nitriles of aldonic acids

1. By the action of pyridine-propionic anhydride on some oximes of monosaccharides a series of propionylated nitriles of aldonic acids have been prepared. 2. The oximes employed reacted with preference in an aldo form, as shown by the high yields of nitriles obtained. l-Rhamnose oxime reacted only i...

Degradation of the nitriles with ammonia-silver oxide gave the usual dipropionamide derivative of the lower sugar. 4. Molecular distillation was found to be a good method for the purification of the propionylated nitriles of aldonic acids. Acetylated nitriles can be sublimed without decomposition, but the benzoylated nitriles, while distillable, are partially decomposed. © 1950, American Chemical Society. All rights reserved.
