The main part of this book is the efficient regioselective synthesis of functionalized heterocycles (furans, pyrroles, thiophenes, selenophenes) based on the palladium(0)-catalyzed cross-coupling and metal-halide exchanged reactions of brominated heterocycles. The study of the efficient methodologies (regioselectivities, optimization of condition including catalysts, solvent, temperature ...) to functionalize them to give a valuable synthetic procedure for the synthesis of pharmacologically relevant products and of useful intermediates for further synthetic transformations. These...
