Ureido-derivatized polymers based on both poly(allylurea) and poly(L-citrulline) exhibit UCST-type phase transition behavior under physiologically relevant conditions.
Biomacromolecules 12(10) , 3418-22, (2011) There are few examples of polymers that exhibit upper critical solution temperature (UCST) behavior under physiological conditions of temperature, pH, and ionic strength. In this study, we demonstrated that polymers with ureido groups undergo UCST-type phase ... |

Sequential double α-arylation of N-allylureas by asymmetric deprotonation and N→C aryl migration.
Org. Lett. 12(23) , 5442-5, (2010) On lithiation with lithium amides, N-allyl-N'-aryl ureas undergo rearrangement with transfer of the aryl ring from N to the allylic α carbon. From the α-arylated products, a further aryl transfer under the influence of a chiral lithium amide allows the enanti... |

A new synthesis of imidazolidin-2-ones via Pd-catalyzed carboamination of N-allylureas.
Org. Lett. 8(12) , 2531-4, (2006) A new strategy for the preparation of substituted imidazolidin-2-ones in two steps from readily available N-allylamines is described. Addition of the amine starting materials to isocyanates affords N-allylureas, which are converted to imidazolidin-2-one produ... |

Influence of surface coverage with poly(ethylene oxide) on attachment of sterically stabilized microspheres to rat Kupffer cells in vitro.
Biomaterials 16(6) , 427-39, (1995) The attachment to rat Kupffer cells of polymeric microspheres, sterically stabilized with different amounts of pendant poly(ethylene oxide) (PEO), was assessed in vitro. Four types of copolymer polystyrene (PS) microspheres were synthesized by variation of fo... |

Physical stabilization of starch-allylurea blends by EB-grafting: a compositional and structural study.
Biomacromolecules 1(2) , 282-9, (2000) A structural and compositional study of thermoplastic blends prepared from native potato starch (NPS) and various amounts of allylurea (AU) was performed to gain a better understanding of possible radiochemical routes to physically stable materials. The blend... |

Compatibilization of starch-allylurea blends by electron beam irradiation: spectroscopic monitoring and assessment of grafting efficiency.
Biomacromolecules 2(4) , 1260-6, (2001) The chemical changes induced by electron-beam irradiation of mixtures of N-allylurea (AU) and amorphized starch were studied by spectroscopic methods for identifying and monitoring the reactions providing the blend with stabilized physical properties. Spectra... |

Synthesis of homoveratric acid-imprinted polymers and their evaluation as selective separation materials.
Molecules 16(5) , 3826-44, (2011) A bulk polymerization method was used to easily and efficiently prepare homoveratric acid (3,4-dimethoxyphenylacetic acid)-imprinted polymers from eight basic monomers: 2-vinylpyridine, 4-vinylpyridine, 1-vinylimidazole, N-allylaniline, N-allylpiperazine, all... |
