The vicariousnucleophilicsubstitution of hydrogen in N-substituted 2-nitropyrrole with carbanion of chloromethyl phenyl sulfone occurs at position 5- or 3- depending upon electronic effects of the N-protecting group.

In the method for introducing a noncanonical amino acid residue into a desired position in a protein, the structure of tRNA is so modified as to have improved affinity for aminoacyl-tRNA synthetase or improved specificity to aminoacyl-tRNA synthetase. An unnatural base is contained at any position in tRNA, whereby the efficiency of aminoacylation of the tRNA with a noncanonical amino acid can be improved.
