Copper-diamine-catalyzed N-arylation of pyrroles, pyrazoles, indazoles, imidazoles, and triazoles.
J. Org. Chem. 69 , 5578, (2004) This paper details the copper-catalyzed N-arylation of pi-excessive nitrogen heterocycles. The coupling of either aryl iodides or aryl bromides with common nitrogen heterocycles (pyrroles, pyrazoles, indazoles, imidazoles, and triazoles) was successfully perf... |

Conversion of cysteinyl residues to unnatural amino acid analogs. Examination in a model system.
J. Protein Chem. 15(8) , 737-42, (1996) Improved and efficient techniques have led to an explosive growth in the application of site-directed mutagenesis to the study of enzymes. However, the limited availability of only those 20 amino acids that are translated by the genetic code has prevented the... |
