A method for the enantioselectivesynthesis of cis-3-quinuclidinols by Ru-catalyzed asymmetrictransferhydrogenation via dynamic kinetic resolution is described. The reaction proceeded under mild conditions using ammonium formate as the hydrogen donor, affording the products in high yields (up to 99%) with excellent diastereoselectivity (up to 99:1 dr) and enantioselectivity (95–99% ee). This protocol
