Deamination is the removal of an amino group from a molecule. Enzymes that catalyse this reaction are called deaminases. In the human body, deamination takes place primarily in the liver, however it can also occur in the kidney. In situations of excess protein intake, deamination is used to break down amino acids for energy. The amino group is removed from the amino acid and converted to ammonia. The rest o… Webthe hydrodeamination products were identified by GC-MS (especially for p-anisidine). To avoid the formation of acetanilides and minimizes the hydrodeamination reaction we decided to explore the performance of trimethylsilyl enol ethers in the reaction with electron-richer anilines, under otherwise similar conditions.
