Carbamate chemistry
Ammonium carbamate is a chemical compound with the formula [NH4][H2NCO2] consisting of ammonium cation NH+4 and carbamate anion NH2COO . It is a white solid that is extremely soluble in water, less so in alcohol. Ammonium carbamate can be formed by the reaction of ammonia NH3 with carbon dioxide CO2, and will slowly decompose to those gases at ordinary temperatures an… WebThe formation of Boc-protected amines and amino acids is conducted under either aqueous or anhydrous conditions, by reaction with a base and the anhydride Boc 2 O. Active esters and other derivatives such as Boc-ONH 2 and Boc-N 3 can also be used. The Boc group is stable towards most nucleophiles and bases. Therefore, an orthogonal protection ...
