Suzuki. Heck and Sonogishira coupling reactions of paramagnetic vinyl bromides 1-6 gave monofunctional (7a,b), homobifunctional (8a,b, 24), and heterobifunctional pyrroline nitroxide; (9-19, 31) under mild conditions in aone-step reaction. From these compounds thiol-specific spin labels 26 and 28 and pyrroline nitroxide annulated heterocycles 30 and 32 were synthesized. The ethynyl derivative of pyrroline
Suzuki reactions are utilized for the synthesis of heterobifunctional cross-linking reagents (thiol- or aminospecific and photoactivatable), polyaromatics (such as phenanthrene) and heterocycles (such as coumarin and quinoline), anellated nitroxides and paramagnetic, biologically active molecules (such as cis-stilbene and nicotinamide). Furthermore, the synthesis of new vinyl and allyl boronic acid esters is also reported.
