The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: D-Alanine methylamide hydrochloride, is researched, Molecular C4H11ClN2O, CAS is 61302-99-6, about New Amino Acids for the Topographical Control of Peptide Conformation: Synthesis of All the Isomers of α,β-Dimethylphenylalanine and α,β-Dimethyl-1,2,3,4-tetrahydroisoquinoline-3-carboxylic Acid of High Optical Purity, the main research direction is stereoisomer dimethylphenylalanine asym synthesis conformation; phenylalanine dimethyl stereoisomer preparation conformation; isoquinolinecarboxylic acid dimethyltetrahydro stereoisomer conformation.Safety of D-Alanine methylamide hydrochloride.
The synthesis of all four diastereoisomers of α,β-dimethylphenylalanine, H2NCMe(CHMePh)CO2H, (4) as well as those of α,β-dimethyl-1,2,3,4,-tetrahydroisoquinoline-3-carboxylic acid (I and II) have been accomplished in high yield and high optical purity. Mol. mechanics calculations on the Nα-acetyl and N-methylcarboxamide derivatives of (3R,4R)-I and (3R,4S)-II indicate large and moderate energy stabilization for the gauche(-) but not the gauche(+) side-chain conformers of (3R,4S)-II and (3R,4R)-I, resp. By symmetry rules, the same holds for (3S,4R)-II and (3S,4S)-I, resp. Thus, these amino acids are potential building blocks for the topog. design of peptides (W. M. Kazmierski et al., 1991) by providing acylated 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid derivatives in which a gauche(-) and not a gauche(+) side-chain conformation is energetically more stable for the L-amino acid. Synthetic details and implications of these new amino acids for peptide and protein design are discussed.
This literature about this compound(61302-99-6)Safety of D-Alanine methylamide hydrochloridehas given us a lot of inspiration, and I hope that the research on this compound(D-Alanine methylamide hydrochloride) can be further advanced. Maybe we can get more compounds in a similar way.
