Electric Literature of C5H3IO2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5-Iodo-2-furaldehyde, is researched, Molecular C5H3IO2, CAS is 2689-65-8, about Functionalization of C(sp3)-H bonds using a transient directing group. Author is Zhang, Fang-Lin; Hong, Kai; Li, Tuan-Jie; Park, Hojoon; Yu, Jin-Quan.

Proximity-driven metalation has been extensively exploited to achieve reactivity and selectivity in carbon-hydrogen (C-H) bond activation. Despite the substantial improvement in developing more efficient and practical directing groups, their stoichiometric installation and removal limit efficiency and, often, applicability as well. Here we report the development of an amino acid reagent that reversibly reacts with aldehydes and ketones in situ via imine formation to serve as a transient directing group for activation of inert C-H bonds. Arylation of a wide range of aldehydes and ketones at the β or γ positions proceeds in the presence of a palladium catalyst and a catalytic amount of amino acid. The feasibility of achieving enantioselective C-H activation reactions using a chiral amino acid as the transient directing group is also demonstrated.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Novel Allosteric Ligands of γ-Aminobutyric Acid Transporter 1 (GAT1) by MS Based Screening of Pseudostatic Hydrazone Libraries, published in 2018-11-21, which mentions a compound: 2689-65-8, mainly applied to nipecotic acid pseudostatic hydrazone library preparation GAT1 allosteric ligand, Recommanded Product: 2689-65-8.

This study describes the screening of dynamic combinatorial libraries based on nipecotic acid as core structure with substituents attached to the 5- instead of the common 1-position for the search of novel inhibitors of the GABA transporter GAT1. The generated pseudostatic hydrazone libraries included a total of nearly 900 compounds and were screened for their binding affinities toward GAT1 in competitive mass spectrometry (MS) based Binding Assays. Characterization of the hydrazones with the highest affinities (with cis-configured compound I bearing a 5-(1-naphthyl)furan-2-yl residue and a four atom spacer being the most potent) in binding and uptake experiments revealed an allosteric interaction at GAT1, which was not reported for any other nipecotic acid derivative up to now. Therefore, the herein introduced 5-substituted nipecotic acid derivatives could serve as valuable tools for investigations of allosterically modulated GABA transport mediated by GAT1 and furthermore as starting point for a new class of GAT1 inhibitors.

In some applications, this compound(2689-65-8)Recommanded Product: 2689-65-8 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
