Reaction of sugar oxazolines with primary amines. In order to scrutinize the reaction pathway and structure of the reaction product, we started with a simple sugar oxazoline and a primary amine, carrying no other functional groups.
1 Aliphatic amines exhibit momentous solubility in organic solvents, particularly in polar organic solvents. 2  The aromatic amines such as aniline, do not take part in the hydrogen bonding. Due to this, their boiling points are high and their solubility in water is very low.
