Two phenyls are better than one or three: synthesis and application of terminal olefin-oxazoline (TOlefOx) ligands†
Abstract
A novel terminal olefin-oxazoline ligand was introduced into rhodium-catalyzed asymmetric conjugate addition of arylboronic acids to enones and gave excellent enantioselectivities. The two phenyls proved better than one or three in ligand evaluations.
