Synthesis, Radioiodination and Biodistribution Evaluation of 5-(2-amimo-4-styryl pyrimidine-4-yl)-4-methoxybenzofuran-6-ol
This study describes the organic synthesis of 5-(2-amimo-4-styryl pyrimidine-4-yl)-4-methoxy benzofuran-6-ol (SPBF) as an example of a benzofuran derivative used as a new series of amyloid imaging agents. These benzofuran derivatives may be useful amyloid imaging agents for detecting B-amyloid plagues in the brain of Alzheimer’s disease. The precursor is 1-[6-hydroxy-4-methoxybenzofuran-5-yl]-p...

متن کامل6-(4-Fluorophenethyl)-7-imino-3-phenyl-2,3,6,7-tetrahydro-1,3-thiazolo[4,5-d]pyrimidine-2-thione
In the title compound, C(19)H(15)FN(4)S(2), the mean plane of the thia-zolopyrimidine makes a dihedral angle of 77.6 (1)° with the attached phenyl ring. The crystal packing is stabilized by inter-molecular C-H⋯N hydrogen bonds and weak C-H-π stacking inter-actions.
متن کاملOne Step Synthesis of 6-Amino-5-Cyano-4-Phenyl-2-Mercapto Pyrimidine Using Phosphorus Pentoxide
A simple and efficient approach towards one step synthesis of 6-amino-5-cyano-4-phenyl-2-mercapto pyrimidine and its hydroxyl derivatives have been developed by three component condensation of aromatic aldehydes, malononitrile and thiourea/urea in presence of phosphorus pentoxide (Scheme 1).
متن کاملCyclohexanespiro-2′-[2′,3′,6′,7′-tetrahydro-1′H-cyclopenta[d]pyrimidin]-4′(5′H)-one
The title compound, C(12)H(18)N(2)O, was synthesized by the reaction of cyclo-hexa-none and 2-amino-cyclo-pent-1-enecarbonitrile. In the mol-ecule of the title compound, the six-carbon ring displays a chair conformation, the six-membered 1,3-diaza ring and the cyclo-pentene ring both assume envelope conformations. Supra-molecular aggregation is achieved by N-H⋯O hydrogen bonds.
