A new serotonin (5-hydroxytryptamine) metabolite, (4R)-2-[(5?-hydroxy-1?H-indol-3?-yl)methyl]thiazolidine-4-carboxylic acid (5?-HITCA), was synthesized in 30% overall yield. The key step involved oxidation of protected 5-hydroxytryptophol using IBX followed by spontaneous cyclization with l-cysteine. The stereochemistry of condensation product thiazolidine-4-carboxylic acid was studied using NMR spectroscopy techniques.
