  • Patent number: 8361169
    Abstract: Various methods for forming dyed microspheres are provided. One method includes activating a chemical structure coupled to a dye using heat or light to form a reaction intermediate in the presence of a microsphere. The reaction intermediate covalently attaches to a polymer of the microsphere thereby coupling the dye to the polymer and forming the dyed microsphere. Additional methods are provided for forming a dyed microsphere coupled to a molecule. These methods include dyeing the microspheres as described above in addition to synthesizing the molecule on an outer surface of the dyed microspheres. A population of dyed microspheres is also provided. Each of the dyed microspheres of the population includes a dye attached to a polymer of each of the dyed microspheres by a chemical structure. A coefficient of variation in dye characteristics of the population of dyed microspheres attributable to the dye is less than about 10%.

  • Publication number: 20120101271
    Abstract: Selective intramolecular C—H amination via metalloradical activation of azides: synthesis of 1,3-diamines under neutral and nonoxidative conditions. One aspect of the present invention is the synthesis of 1,3-diamines by intramolecular C—H amination of sulfamoyl azides. More specifically, sulfamoyl azides may be selectively aminated via metalloradical activation of azides, preferably with Co(II) porphyrins. In a particularly preferred embodiment, the Co(II) porphyrin is a D2h-symmetric porphyrin.

  • Patent number: 7301006
    Abstract: Methods and protected amino acids useful as building blocks (protected monomers) for the synthesis of peptides and proteins that are selectively modified at one or more side-chain hydroxyl groups. Azide-bearing protecting groups allow the selective deprotection of side-chain hydroxyl groups of amino acids after synthesis of a peptide. Reaction conditions for removal of the azide-bearing protecting group can be selected which are substantially orthogonal to those that will remove ?-amino protecting groups typically employed in peptide synthesis, such that hydroxyl groups protected with the azide-bearing protecting group remain protected during synthesis of the peptide chain. Various protecting groups which are readily available can be used for protecting potentially reactive side chain groups of amino acids in the peptide or protein to be modified.
