Methyl 2-tert-butoxycarbonylaminoacrylate

CAS 55477-80-0

Methyl 2-tert-butoxycarbonylaminoacrylate (CAS 55477-80-0) illustrates how molecular structure determines chemical role. Methyl 2-(tert-butoxycarbonylamino)acrylate is a protected dehydroamino-acid derivative combining an activated double bond, a methyl ester, and a Boc-protected nitrogen. The Boc group masks the amino function during bond-forming reactions and can later be removed under acidic conditions. The electron-deficient unsaturated ester can participate in addition, reduction, substitution, and carbon-carbon bond-forming sequences. Compounds of this type are useful in amino-acid and heterocycle synthesis because chemists can introduce substituents around a future amino-acid framework while controlling when nitrogen becomes reactive. Public exact-CAS literature is mainly synthetic, so it is best described as a building block rather than assigned an independent therapeutic role. Exact CAS identity matters when distinguishing related chemical forms and their documented applications.
