Synthesis of picolinates via a cooperative vinylogous anomeric-based oxidation using UiO-66(Zr)-N(CH₂PO₃H₂)₂ as a catalyst

Abstract

The architecture of porous solid catalyst based on Zr-MOFs for the synthesis of picolinates via a cooperative vinylogous anomeric-based oxidation.

Design, synthesis and application of a magnetic H-bond catalyst in the preparation of new nicotinonitriles via cooperative vinylogous anomeric-based oxidation

“…[36][37][38] Our research group has recently explored the application of AE to explain the activities of organic molecules. [39][40][41][42][43] Expanding the design of heterogeneous catalysts is one of the main goals of this report. The importance of magnetic nanoparticles-based catalysts has prompted us to introduce Fe 3 O 4 @SiO 2 @tosyl-carboxamide as a new magnetic H-bond catalyst.…”

A novel pillar-layered MOF with the urea linkers: A capable catalyst for the synthesis of new 1,8-naphthyridines via the anomeric-based oxidation

“…[25][26][27][28] The anomeric effect (negative hyperconjugation) can lead to the generation of nal products through sharing none bonded lone pairs electrons of heteroatom into the anti-bonding orbitals of the C-H bond without employing an oxidation agent. 29,30 The ability of the anomeric effect in the mechanistic aspects of the reaction can be observed in the tricyclic orthoamide, which leads to the release of hydrogen by unusual hydride transfer (Scheme 3). 31 Continuing our previous study on the synthesis and applications of the urea-based catalysts (the Basuframework) 32,33 , we decided to synthesize Basu-HDI as a novel heterogeneous catalyst.…”
