(1)H and (13)C NMR Assignments of Cytotoxic 3S-1,2,3,4-Tetrahydro-β-carboline-3-carboxylic Acid from the Leaves of Cichorium endivia
An amino acid, 3S-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid, was isolated for the first time from the leaves of Cichorium endivia. The complete assignment of its (1)H and (13)C NMR spectroscopic data was carried out also for the first time based on extensive 1D and 2D NMR experiments. Cytotox...
