Abstract
This paper describes an asymmetric hydrogenation of 1,3-disubstituted isoquinolines catalyzed by chiral borane derived from chiral alkene, giving the desired cis-products in high yields with up to 96% ee. In particular, the asymmetric hydrogenation of challenging 1,3,4-trisubstituted isoquinolines could proceed smoothly to afford the corresponding products in high yields with moderate ee’s for the first time.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
