Recommanded Product: (S)-2-Bromosuccinic acid. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: (S)-2-Bromosuccinic acid, is researched, Molecular C4H5BrO4, CAS is 20859-23-8, about Reaction of ammonia with optically active halogenated carboxylic acids supported on anion exchange resin. Author is Urata, Yoshikiyo.
The exchange degrees of Amberlyst A-26 (OH form) treated with L-α-chloro-(I) and L-α-bromosuccinic acid (II) were 70 and 58%, resp., dehydrobromination of II to fumaric acid was also observed L-Aspartic acid, prepared from I via the L-α-chlorosuccinate form of the resin by treatment with NH3-MeOH, aqueous NH3, liquid NH3, and NH3(g) was more optically active than the L-aspartic acid obtained by the direct treatment of I with NH3. The rearrangement during the substitution reaction of NH3 with the L-α-chlorosuccinate form of the resin occurred with configurational retention. The effect of the macro-mol. structure on this reaction was discussed.
There is still a lot of research devoted to this compound(SMILES：O=C(O)[C@@H](Br)CC(O)=O)Recommanded Product: (S)-2-Bromosuccinic acid, and with the development of science, more effects of this compound(20859-23-8) can be discovered.
