Self-assembling of dihydroxypropyl 5,6-dihydrothymine derivatives
摘要:
(R, S)-1-(2',3'-Dibenzoyloxypropy1)-5,6-dihydrothymine (2) was synthesized from (R, S)-1-(2',3'-dihydroxypropy1)-5,6-dihydrothymine and its structure has been analyzed by X-ray diffraction, NMR and FTIR spectroscopic methods. The molecular structure and supramolecular assembling of 2 is compared with the structure of its dimesyloxypropyl analogue (1). Compound 1 crystallizes as cocrystal of two diastereoisomers, while 2 crystallizes as a racemic mixture. Main hydrogen-bonded motif in both compounds is dimer formed by pair of N H--.0() hydrogen bonds, which are further linked by C H--.0 hydrogen bonds. Phenyl rings of dibenzoyl-dihydropyrimidine moieties of 2 participate also in supramolecular aggregation via three C H it interactions. Hydrogen bonding as driving force of 2 self-assembly was proving by the NMR and FTIR spectroscopy. (C) 2010 Elsevier B.V. All rights reserved.
1-substituted uracil and thyminederivatives have been developed. The aminolysis of 2- or 4-nitrophenyl 3-ethoxyacryloylcarbamate and 3-ethoxy-2-methylacryloylcarbamate with a variety of primary amino derivatives proceeded smoothly under very mild reaction conditions yielding almost quantitatively the 1,3-disubstituted urea derivatives. Their subsequent cyclization provided the 1-substituted uracil and thymine

Novel ethylene glycol compounds bearing various functional groups are used to prepare oligomeric structures. The ethylene glycol monomers can be joined via standard phosphate linkages including phosphodiester and phosphorothioate linkages. Useful functional groups include nucleobases as well as polar groups, hydrophobic groups, ionic groups, aromatic groups and/or groups that participate in hydrogen-bonding.
