Exempel på hur man kan använda HEMIAMINAL i en mening

• Schiff bases can be synthesized from an aliphatic or aromatic amine and a carbonyl compound by nucleophilic addition forming a hemiaminal, followed by a dehydration to generate an imine.
• Upon addition of a N,N-disubstituted formamide (such as dimethylformamide) a hemiaminal is formed, which can easily be hydrolyzed into the desired aldehyde.
• In the next step the nitrogen to carbon double bond (imine) is reduced with sodium borohydride and the resulting oxazine (a hemiaminal) hydrolyzed with water and oxalic acid to the aldehyde.
• The nitrogen of the iminosugar ring structure is a hemiaminal linkage, which, like the hemiacetal of a regular glycoside, is unstable.
