Experimental and Computational Studies in Bioorganic and Synthetic Organic Chemistry
Cationâ Ï interaction is an important determinant in protein structure and function. Among the three proteinogenic aromatic amino acids, tryptophan (Trp) is the strongest cationâ Ï donor. We reported the asymmetric syntheses of tryptophan regioisomers in which the amino acid side chain is attached …
