title: Studies on the synthesis of the fluorescent bases from phenylalanine transfer ribonucleic acids.
abstract: L-Serine has been transformed into (R)-[2-carboxy-2-[(methoxycarbonyl) amino]ethyl]triphenylphosphonium chloride in seven steps. The Wittig reaction of this compound with 1-benzyl-7-formylwye followed by successive methylation and reduction has produced (S)-wybutine.
