Paragraph 0167, (2017/06/12)
Parts of compounds, after being labeled by radionuclide, of the phenyl benzyl ether derivative, are used as Aβ plaque imaging agent. The structural formula of the phenyl benzyl ether derivative is shown by formula (I). The present invention develops a kin

A novel terminal thioacetate-substitued alkoxy piperazine was successfully synthesized from 4-(benzyloxy)phenol after six-step reaction and employed as the surface-active material in fabrication of self-assembled monolayers (SAMs). Cyclic voltammetric (CV) results showed that the SAM-modified gold electrode had special capacity in recognition for Fe3+.

Three new substituted tetraphenylene crown ethers have been made. Bis(5- carbomethoxy-1,3-phenylene)-bis(p-phenylene)-(3x + 6)-crown-x, where x = 12, 16, and 20 (11b-11d) were synthesized via [1 + 1] cyclization of methyl 3,5- bis[ω-chloro(oligoethyleneoxy)]benzoates (13b-3d) with methyl 3,5-bis[ω- (p-hydroxyphenoxy)(oligoethyleneoxy)]benzoates (16b-6d) using K2CO3 as base and tetrabutylammonium iodide as a phase transfer agent in dimethylformamide (DMF). The corresponding 30-membered (x = 8) macrocycle 11a could not be made by this approach; only the elimination product, 3,5-bis(vinyloxy)benzoic acid (19), was isolated. 16a-16d were made via alkylation of p-benzyloxyphenol (14) with 13a-13d, respectively, followed by hydrogenolysis with Pd/C as catalyst. No complexation of these macrocycles with dibenzylammonium ions was detected by NMR spectroscopy, but weak complexation of 11d with a paraquat derivative was observed.
