| | D-1,2,3,4-Tetrahydroisoquinoline-3-carboxylic acid Usage And Synthesis |
| Description | D-1,2,3,4-Tetrahydroisoquinoline-3-carboxylic acid ((3R)-1,2,3,4-Tetrahydroisoquinoline-3-carboxylic acid) is a magnetic, neutral compound. It is used as a pharmacological study to investigate the reaction mechanism and kinetics of the deuteration process. The asymmetric synthesis of D-1,2,3,4-Tetrahydroisoquinoline-3-carboxylic acid has been investigated using vinylene chloride and hydantoin as reactants. There are various parameters that affect the kinetics of this reaction such as solvent type and temperature. The nitric oxide synthase inhibitor activity of D-1,2,3,4-Tetrahydroisoquinoline-3-carboxylic acid has been studied in vitro. Results have shown that it inhibits nitric oxide synthase by binding to the heme iron of the enzyme and preventing the conversion of arginine | | Chemical Properties | White solid | | Uses | (R)-1,2,3,4-Tetrahydroisoquinoline-3-carboxylic Acid, is an amino acid building block used in peptide synthesis. With a growing peptide drug market the fast, reliable synthesis of peptides is of great importance. | | Definition | ChEBI: D-1,2,3,4-Tetrahydroisoquinoline-3-carboxylic acid is a member of isoquinolines. | | Synthesis | General procedure for the synthesis of (R)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid from formaldehyde and D-phenylalanine:
1. Preparation of (3R)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid: D-phenylalanine (50 g, 0.3 mol), concentrated hydrochloric acid (386 mL), and 37% wt formalin (113.7 mL) were mixed, and the reaction was carried out for 4 h at 95 °C with vigorous stirring. Upon completion of the reaction, the mixture was cooled to room temperature and stirring was continued for 2 hours. The reaction mixture was filtered and the precipitate was washed with cold water to afford (3R)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (25 g, 42% yield) in white solid form.
2. Esterification reaction: benzyl alcohol (64 g) and p-toluenesulfonic acid (26.9 g) were added to the above product, and the reaction was carried out under reflux in a Dean-Stark apparatus with benzene (400 mL) as solvent. After completion of the reaction, the solvent was removed in vacuum and the crude product was ground with ether to obtain a solid, which was subsequently recrystallized with water and methanol to give (R)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (28 g, 35% yield) in white solid form. | | References | [1] MedChemComm, 2014, vol. 5, # 9, p. 1381 - 1383
