La creciente demanda de compuestos enantioméricamente puros para su uso como fármacos, aromas, fragancias, productos agroquímicos y precursores de materiales poliméricos ha impulsado el desarrollo espectacular de la síntesis asimétrica moderna. Hoy en día la síntesis enantioselectiva se enfrenta al reto de desarrollar metodologías que combinen...

The geometries and coordination properties of modular pyridineehydrazone N,N-ligands containing C2- symmetric trans-2,5-diphenylpyrrolidine and trans-2,5-diphenylpiperidine as the terminal dialkylamino units have been analyzed by X-ray diffraction analysis of [PdCl2(N,N)] complexes [(N,N)¼pyridine hy- drazone ligand]. In combination with...

Catalysts generated by combinations of Pd(TFA)2 and enantiomerically pure pyridine-hydrazone ligands have been applied to the 1,4-addition of arylboronic acids to β-substituted cyclic enones, building all-carbon quaternary stereocenters in high yields and enantioselectivities (up to 93% ee). The developed methodology allows the efficient...
