(E)-Specific direct Julia-olefination of aryl alcohols promoted by bases: a strategy of self-hydride transferring redox process.
The present invention generally relates to various compounds that are useful as α-synuclein ligands. The invention further relates to methods of using these compounds and their radiolabeled analogs for the detection of synucleinopathies, including Parkinson's disease (PD).

This paper describes the synthesis of a new class of [N,P] ligands based on pyrrole with a dimethylamino group as hard donor and a phosphine moiety as soft base. We have also modified the phosphine fragment to change the electronic and steric properties of these ligands. Palladium complex 3a proved to be very efficient in Heck cross-coupling reactions and in intramolecular aryl–aryl couplings of esters
