Cross-dehydrogenative coupling and oxidative-amination reactions of ethers and alcohols with aromatics and heteroaromatics
Cross-dehydrogenative coupling (CDC) is a process in which, typically, a C-C bond is formed at the expense of two C-H bonds, either catalyzed by metals or other organic compounds, or via uncatalyzed processes. In this perspective, we present various modes of C-H bond-activation at sp3 centers adjacent to ether oxygen atoms, followed by C-C bond formation with aromatic systems as well as with he...
متن کاملCobalt-catalysed site-selective intra- and intermolecular dehydrogenative amination of unactivated sp3 carbons
Cobalt-catalysed sp(2) C-H bond functionalization has attracted considerable attention in recent years because of the low cost of cobalt complexes and interesting modes of action in the process. In comparison, much less efforts have been devoted to the sp(3) carbons. Here we report the cobalt-catalysed site-selective dehydrogenative cyclization of aliphatic amides via a C-H bond functionalizati...
متن کاملEosin Y dye-based porous organic polymers for highly efficient heterogeneous photocatalytic dehydrogenative coupling reaction
Construction of porous organic polymers (POPs) as metal-free heterogeneous organic photocatalysts for highly efficient catalytic organic transformations using visible light remains a key challenge. Herein, we report the “bottom-up” strategy to facilely synthesize two Eosin Y dye-based POP frameworks (EY-POPs) for highly efficient heterogeneous organic-photocatalysis. Owing to the high BET surfa...
متن کاملPhotocatalytic reversible amination of α-keto acids on a ZnS surface: implications for the prebiotic metabolism.
We report the enzyme-like reversible amination of four intermediates pertinent to the reductive tricarboxylic acid cycle on a photo-irradiated surface of mineral sphalerite (ZnS). Given its prevalence in the waters of early Earth, we suggest that the mineral-based photochemistry might have catalyzed the homeostasis of prebiotic metabolic systems.
متن کاملTransamination and Reductive Amination
Æ-Keto acids can be reductively aminated to Æ-amino acids via amino acid dehydrogenase catalysis, with NAD(P)H as cofactor. The nitrogen source for the amine functionality is ammonia, the least expensive source. Regeneration of the co-factor NAD(P)+ back to NAD(P)H is required for synthesis and is commonly afforded via formate dehydrogenase catalyzed oxidation of formate to carbon dioxide or gl...
