Significance

Asymmetric hydrogenation of ­heterocycles is a challenging transformation due to the need to destroy aromaticity. The authors have previously developed a method for activating unprotected indoles for hydrogenation (J. Am. Chem. Soc. 2010, 132, 8909). In the present report, they utilize 3-(α-hydroxyalkyl)indoles, which can be activated by dehydration, allowing for a highly enantioselective palladium-catalyzed ­hydrogenation to take place.
