A New Pyridyl Bis(oxazoline) Ligand Prepared from D-Glucosamine for Asymmetric Alkynylation of Imines

A New Pyridyl Bis(oxazoline) Ligand Prepared from D-Glucosamine for Asymmetric Alkynylation of Imines

A new carbohydrate‐based pyridyl bis(oxazoline) has been prepared from D‐glucosamine via simple steps. With this ligand enantioselectivities up to 99% were achieved in copper(I)‐catalysed alkynylations of imines.
