Preparation and pharmaceutical evaluation for clinical application of high specific activity S-(−)[11C]CGP-12177, a radioligand for &bgr;-adrenoreceptors
This study attempted to prepare S-(−)[11C]CGP-12177 formulated for intravenous injection with high purity and high specific activity, which is feasible for the clinical evaluation of &bgr;-adrenoreceptors. Expand
[Synthesis of 18F-FDG with FDG MicroLab system: basic studies for clinical application].
The automated synthetic apparatus "FDG MicroLab" has proven to stably produce 18F-FDG with high yield and high purity and is feasible for routine clinical production of 18F -FDG. Expand
Electrocyclic Rearrangement of Pentamethylcyclooctapyrimidine-2,4-diones: Reaction Pathway into a 9,11-Diazapentacyclo-[,3.02,5.04,8]dodecane System and a 9,11-Diazapentacyclo
Abstract Photolysis of 6-chloro-1,3-dimethyluracil and mesitylene in the presence of trifluoroacetic acid (TFA) at low temperature gave 1,3,5,7,9- andExpand
Photocycloaddition of 6-chloro-1,3-dimethyluracil to benzene.
Effects of substituents on the acid-catalyzed photoreaction of pyrimidine derivatives in p-xylene.
In order to obtain insight into the protonation of the electron adducts of pyrimidine bases and the chemical behavior of the resulting radicals under an acidic condition, the photoreaction of 5-substituted 1,3-dimethyluracil was performed in p-xylene in the presence of a large amount of trifluoroacetic acid.

Photochemical Synthesis of a Pyridopyrrolo [2, 1-α] isoindole System by Cyclization of N-Methylpyridylphthalimides
Photochemical reactions of N-methylpyridylphthalimides (VII-IX) were investigated. Although irradiation of VII in an acetone solution gave only the dihydro product, 3-hydroxy-2-(3-methyl-2-pyridyl)Expand
Synthesis of Diruthenium μ-Chloromethylidyne Complex: C–C Bond Formation at the Bridging Carbon Atom via the Reduction of a μ-Chloromethylidyne Ligand
The μ-chloromethylidyne complex, [(Cp*RuCl)2(μ-CCl)(μ-Cl)] (2) (Cp* = η5-C5Me5), was prepared by the reaction of a triruthenium pentahydrido complex, [{Cp*Ru(μ-H)}3(μ3-H)2] (1), with CCl4. The reac...
