Visible light-induced direct alpha C?H functionalization of alcohols

Considering the synthetic value of introducing active alcoholic hydroxyl group, developing C?H functionalization of alcohols is of significance. Herein, we present a photochemical method that under visible light irradiation, selectfluor can effectively promote the oxidative cross-coupling between alcohols and heteroarenes without the external photocatalysis, achieving the selective alpha sp3 C?H arylation of alcohol, even in the presence of ether. The N-F activation of selectfluor under blue LEDs irradiation is evidenced by electron paramagnetic resonance (EPR) study, which is the key process for the oxidative activation of alpha sp3 C?H alcohols. The observed reactivity may have significant implications for chemical transformations.

New N-aryl-N?-(3-(substituted)phenyl)-N?-methylguanidines as leads to potential PET radioligands for imaging the open NMDA receptor

An expansive set of N-aryl-N?-(3-(substituted)phenyl)-N?-methylguanidines was prepared in a search for new leads to prospective PET ligands for imaging of the open channel of the N-methyl-d-aspartate (NMDA) receptor in vivo. The N-aryl rings and their substituents were varied, whereas the N-methyl group was maintained as a site for potential labeling with the positron-emitter, carbon-11 (t1/2 = 20.4 min). At micromolar concentration, over half of the prepared compounds strongly inhibited the binding of [3H]TCP to its binding site in the open NMDA receptor in vitro. Four ligands displayed affinities that are similar or superior to those of the promising SPECT radioligand ([123I]CNS1261). The 3?-dimethylamino (19; Ki 36.7 nM), 3?-trifluoromethyl (20; Ki 18.3 nM) and 3?-methylthio (2; Ki 39.8 nM) derivatives of N-1-naphthyl-N?-(phenyl)-N?-methylguanidine were identified as especially attractive leads for PET radioligand development.

Synthesis of N-substituted benzo[c][1,7]- and benzo[c][1,8] phenanthrolin-(5H)-6-ones through a Pd-mediated Suzuki-Miyaura heteroaryl-aryl coupling reaction

In the course of the search for non-camptothecin topoisomerase I inhibitors we have undertaken the synthesis of N-substituted benzo[c][1,7]- and benzo[c][1,8]phenanthrolinone derivatives. An intermolecular Suzuki-Miyaura heteroaryl-aryl coupling reaction was planned as the key step. Then a nitro reduction followed by a concomitant lactamization achieved the construction of the tetracycle structures. This methodology permitted a rapid and efficient elaboration of biologically potent compounds.

Direct synthesis of 3-arylpropionic acids by tetraphosphine/palladium catalysed Heck reactions of aryl halides with acrolein ethylene acetal

Through the use of [PdCl(C3H5)]2/Cis,cis, cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane as a catalyst, a range of aryl bromides undergoes Heck reaction with acrolein ethylene acetal. With this acetal, the selective formation of 3-arylpropionic acids/esters was observed. The functional group tolerance on the aryl halide is remarkable; substituents such as fluoro, methyl, methoxy, acetyl, formyl, benzoyl, nitro or nitrile are tolerated. Furthermore, this catalyst can be used at low loading, even for reactions of sterically hindered aryl bromides. Graphical Abstract.

Oxazolidines as Intermediates in the Asymmetric Synthesis of 3-Substituted and 1,3-Disubstituted Tetrahydroisoquinolines

A diastereoselective mercury(II)-promoted intramolecular cyclization of unsaturated aldehyde via an oxazolidine to prepare C-3-substituted tetrahydroisoquinoline is disclosed. The C-3 stereogenic center is subsequently exploited to create the C-1 stereocenter by coordination of the nucleophilic reagent to the oxygen atom of oxazolidine. Both cis- and trans-1,3-disubstituted tetrahydroisoquinolines can be readily prepared. In addition, when a cationic rhodium complex was used, intramolecular hydroamination was effected, thus avoiding mercury(II) salts and demercuration. The reaction is general and works well using aliphatic and aromatic aldehydes.

Ir(III) complex-based phosphorescence and electrochemiluminescence chemodosimetric probes for Hg(II) ions with high selectivity and sensitivity

Mercury, one of the most prevalent toxic metal elements, poses severe risks to human health and the environment. Several molecular probes have been developed for colorimetric and fluorometric detection of Hg(ii) ions. Nevertheless, development of a rapid, selective, and sensitive probe for Hg(ii) ions remains important. Herein, we report three Ir(iii) complex-based phosphorescence and electrochemiluminescence chemodosimeters for the selective detection of Hg(ii) ions. The acetylacetonate ancillary ligand of probe 1 reacts selectively with the Hg(ii) ion, inducing phosphorescence enhancement with a concomitant blue-shift. Meanwhile, the Hg(ii) ion selectively quenches the phosphorescence of probe 2. Probes 1 and 2 showed low detection limits (LOD) of 73 and 160 nM, respectively. In addition, the Hg(ii) ion level was successfully monitored by the electrochemiluminescence decrement of probe 9 with a good linear correlation between 0 and 40 muM, with a detection limit of 170 pM.
