Efficient Conversion of N-Terminal of L-Tyrosine, DL-Phenyl Alanine, and Glycine to Substituted 2-Thioxo-thiazolidine-4-ones: A Stereospecific Synthesis
摘要:
We report facile and efficient conversion of the amino functional group of amino acids such a s L-tyrosine, DL-phenylalanine, and glycine to the corresponding (+/-)-2-t-hioxo-thiazolidine-4-ones (rhodanines). Stereospecific synthesis of amino acid-incorporated rhodanine is achieved in the case of L-tyrosine. Knoevenagel condensation over the active methylene group at the fifth position of the corresponding rhodanines is also described. The substituted rhodanine incorporated with tyrosine in the form of a dimer connected via two-carbon linker possesses significant anticancer activity against A549 cells (human lung cancer cells).
