A simple quick route to fullerene amino acid derivatives

Abstract

Two new fullerene amino acids have been prepared by dipolar addition to C₆₀ of either the Boc- or Fmoc-Nα-protected azido amino acids derived from phenylalanine and lysine. UV-visible and CV studies indicate the as prepared amino acids are a mixture of 5,6-open (major product) and 6,6-closed (minor product) derivatives that may be readily separated.
