Abstract
The modified nucleosides or bases from transfer ribonucleic acids and related compounds are reviewed from an organic chemical standpoint with particular emphasis on the fluorescent minor components of eukaryotic phenylalanine transfer ribonucleic acids (tRANsPhe). Structural educidations, syntheses, and chemical properties of these unique tricyclic compounds as well as the use of the chemical properties for modifications of yeast tRNAPhe at the anticodon loop are summarized.
