In 2011, Nadeau and coworkers [27] developed the first rhodium-catalyzed asymmetric arylation of N-benzyl nicotinate stJts (other C=N double bond substrates) with arylboronic acids. The use of an axial chiral bisphosphane ligand (i )-CTH-P-Phos gave a variety of six-substituted dihydropy-ridines with excellent enantioselectivities (Scheme 6.22). The usefulness of the method lies on the facile conversion of the dihydropyridines into the synthetically useful piperidines.
