After the solution is evaporated, the residual is dissolved in EtOAc. The solution is washed with 4% NaHCO3, 10% citric acid and water. The solution is dried and evaporated. The purification is carried out by silica gel column chromatography to give Boc-ΔTyr(Cl2Bzl)-Gly-NH2 (317 mg, ...
The amide bond is formed by the elimination of a water molecule (condensation) between the organic groups: COOH (carboxylic acid) and NH2 (amine, not diamine)Another pair of organic groups that will form an amide bond are: COCl (acyl chloride) and NH2 (amine) by elimination of HCl.Now,...
Beisin is a kind of amino acid, and the molecular formula isch3ch (OH) CH (NH2) CO2H. It is a non -refractive structure of amino acid Suspine. Like most other amino acids, sulinine is a water -soluble colorless solid. Although it is not one of the protein primary amino acids, i...
Water soluble condensing reagent. EDAC is generally utilized as a carboxyl activating agent for amide bonding with primary amines. In addition, it will react with phosphate groups. EDAC has been used in peptide synthesis; crosslinking proteins to nucleic acids; and preparation of immunoconjugates as...
The more exothermic reaction energies arise due to the need to make the phosphorus planar in the carbene so that it can donate into the empty p-orbital at the carbene carbon center. The bending potential at the carbene carbon center in the Bertrand compounds is very flat with a large XC:Y...
