Enantioselective organocatalytic reductive amination.
The first enantioselective organocatalytic reductive amination reaction has been accomplished. The development of a new chiral phosphoric acid catalyst has provided a convenient strategy for the enantioselective construction of protected primary amines and provided a highly stereoselective method for the reductive amination of heterocyclic amines. A diverse spectrum of ketone and amine substrat...
متن کاملOrganic synthesis using photoredox catalysis
Natural photosynthesis is a remarkable chemical machinery that enables our life on earth and delivers a constant stream of oxygen and organic biomass. We should acknowledge this fact with humbleness, especially because we have not been able yet to mimic this process in a reliable way even after decades of intense research. The basic mechanistic principle behind photosynthesis is photoredox cata...
متن کاملEnantioselective direct α-amination of aldehydes via a photoredox mechanism: a strategy for asymmetric amine fragment coupling.
The direct, asymmetric α-amination of aldehydes has been accomplished via a combination of photoredox and organocatalysis. Photon-generated N-centered radicals undergo enantioselective α-addition to catalytically formed chiral enamines to directly produce stable α-amino aldehyde adducts bearing synthetically useful amine substitution patterns. Incorporation of a photolabile group on the amine p...
متن کاملHighly enantioselective hydrogen-transfer reductive amination: catalytic asymmetric synthesis of primary amines.
Optically active amines are attracting increasing interest in the food, agrochemical, and pharmaceutical industries as building blocks for novel compounds and as templates for asymmetric synthesis. One of the most common methods for preparing amines is the reductive amination of carbonyl compounds. We have successfully explored the rhodiumcatalyzed asymmetric reductive amination with hydrogen a...
متن کاملPhotoredox Activation and Anion Binding Catalysis in the Dual Catalytic Enantioselective Synthesis of β-Amino Esters.
The enantioselective oxidative C-H functionalization of tetrahydroisoquinoline derivatives is achieved through the merger of photoredox and asymmetric anion-binding catalysis. This combination of two distinct catalysis concepts introduces a potentially general approach to asymmetric transformations in oxidative photocatalysis.
