Preparation of arylphosphinic acid derivatives as building blocks for binding sites [PDF]

open access: yes, 1992
Several members of a new class of potential binding sites have been designed and prepared from a novel bis amino acid, bisphenylalanylphosphinic acid. The synthesis starts by making 4-iodophenylalanine, for which a greatly improved preparation has been ...
