Collection: Precursors for Amino Acid Synthesis
Precursors for Amino Acid Synthesis — a collection of starting compounds and chiral reagents used to build non-proteinogenic amino acids and peptide derivatives, including nickel(II) glycinate Schiff base complexes and thiazolidinone-carboxylic acid derivatives that serve as templates for asymmetric synthesis.
Precursors for Amino Acid Synthesis is used by peptide chemistry and medicinal chemistry researchers to incorporate unnatural amino acid residues into peptide chains through asymmetric synthesis based on nickel(II)-glycinate complexes, a stereoselective alkylation approach that is popular in both academic laboratories and the pharmaceutical industry. Thiazolidinone and imidazolidinone derivatives act as cyclic intermediates or chiral auxiliaries that direct the stereochemistry of the final product before the protecting groups are removed.
Example products in this collection: TCI T1223 19771-63-2 L-2-Thiazolidinone-4-carboxylic Acid, TCI B6108 1004755-00-3 tert-Butyl (R)-2-(2,6-Dichlorophenyl)-5-oxo-3-[(R)-1-phenylethyl]imidazolidine-1-carboxylate, TCI P1738 264921-97-3 [N-[1-[2-(2-Pyridylcarboxamido)phenyl]ethylidene]glycinato]nickel, TCI B6109 1149765-08-1 tert-Butyl (S)-2-(2,6-Dichlorophenyl)-5-oxo-3-[(S)-1-phenylethyl]imidazolidine-1-carboxylate, TCI P1737 847654-17-5 [N-[alpha-[2-(Piperidinoacetamido)phenyl]benzylidene]glycinato]nickel.
Pay attention to the enantiomeric purity and the (R)- or (S)- configuration of chiral auxiliaries such as imidazolidinone derivatives, because this initial stereochemistry determines the final outcome of the asymmetric synthesis; also check the stability of the metal complex against moisture during storage. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.
