CAS 1676-90-0: boc-L-aspartic acid 4-tert-butyl ester

Description:Boc-L-aspartic acid 4-tert-butyl ester is a derivative of aspartic acid, characterized by the presence of a tert-butyl ester group and a Boc (tert-butyloxycarbonyl) protecting group on the amino functionality. This compound is typically used in peptide synthesis and organic chemistry as a protected form of aspartic acid, facilitating the selective reaction of functional groups. It is a white to off-white solid that is soluble in organic solvents such as dichloromethane and dimethyl sulfoxide, but less soluble in water. The Boc group provides stability and protects the amine from unwanted reactions during synthesis, while the tert-butyl ester enhances lipophilicity, aiding in the purification and handling of the compound. The compound's structure allows for the easy removal of the Boc group under mild acidic conditions, regenerating the free amine for further reactions. Overall, Boc-L-aspartic acid 4-tert-butyl ester is a valuable intermediate in the synthesis of peptides and other bioactive molecules.
