number of MPTP and MPP(+) derivatives that are suitable for the comparative neurotoxicity and complexIinhibition versus dopamine metabolism perturbation studies. Structure-activity studies with bovine chromaffin granule ghosts show that 3'-hydroxy-MPP(+) is one of the best known substrates for the vesicular monoamine transporter (VMAT). A series of compounds that combine the structural features of

The efficient and convenient synthesis of various functionalized 4-phenyl-pyridines 2 is described. The key step of the procedure is the electrochemical formation of aromatic organozincreagents 1 and their coupling with pyridinium salts. Intermediate 1,4-dihydropyridines are oxidized using mild conditions to provide functionalized 4-phenyl-pyridines in moderate to high overall yields.
The electrophilic behavior of the reactive entity in the phtosubstitution of benzenes with 2-iodopyridine was found to be ascribable to the intermediary 2-pyridyl cation, rather than to the electrophilic 2-pyridyl radical.

Provided are a vinyl-biphenylpyridine monomer and a polymer thereof. More particularly, the present invention provides a vinyl-biphenylpyridine monomer having a side chain of pyridine or phenylpyridine as a functional group, a homopolymer of which molecular weight and molecular weight distribution are controlled using the monomer, and a block copolymer of which molecular structure and molecular weight are controlled to facilitate synthesis of an organic metal complex. Accordingly, the present invention provides a vinyl-biphenylpyridine monomer and a polymer thereof which are effectively used as nano and optical functional materials.
