Copper-catalyzed: In situ oxidative-coupling for one-pot synthesis of 5-aryl-1,4-disubstituted 1,2,3-triazoles under mild conditions

A new reaction system with CuCl as catalyst, TEA as base and O2/chloramine-T as oxidant was developed for one-pot in situ oxidative-coupling to synthesize 5-aryl-1,4-disubstituted 1,2,3-triazoles in this paper. A variety of 5-arylated-1,2,3-triazole compounds could be efficiently prepared directly from the readily accessible organic azides, terminal alkynes and arylboronic acids. Advantages of the method include use of low-cost catalyst, clean oxidant, less-toxic additive, and low reaction temperature. Importantly, due to avoiding harsh strong basic reagents and high temperatures, the presented method can offer mild conditions for multi-component synthesis of 5-aryl-1,2,3-triazoles from the designed structurally complicated alkynyl or azide donors bearing natural product motifs and sensitive functional groups.

Copper-Catalyzed Decarboxylative Cycloaddition of Propiolic Acids, Azides, and Arylboronic Acids: Construction of Fully Substituted 1,2,3-Triazoles

A copper-catalyzed decarboxylative cycloaddition of propiolic acids, azides, and arylboronic acids is described. The present reaction provides an efficient and convenient method for the synthesis of various fully substituted 1,2,3-Triazoles from readily available starting materials. A possible mechanism is proposed.

Pd-catalyzed ligand-free C(5)–H arylation of 1,4-disubstituted 1,2,3-triazoles promoted by microwaves

Pd(OAc)2-catalyzed regioselective C(5)–H arylation of 1,4-disubstituted 1,2,3-triazoles was achieved without ligand under microwave conditions in 1 h, generating 1,4,5-trisubstituted 1,2,3-triazoles with good to excellent yields. The obtained molecules can be easily converted into 4,5-disubstituted 1,2,3-triazoles through the debenzylation process with one-pot manipulation.

Pd-NHC-catalyzed direct arylation of 1,4-disubstituted 1,2,3-triazoles with aryl halides

A highly efficient method for the synthesis of unsymmetrical multi-substituted 1,2,3-triazoles via a direct Pd-NHC system catalyzed C(5)-arylation of 1,4-disubstituted triazoles, which are readily accessible via "click" chemistry has been developed. It is

N-substituted-1,2,3-triazoles: Synthesis, characterization and evaluation as cannabinoid ligands

A series of new N1-, N2-and N3-substituted 1,2,3-triazole derivatives has been synthesized by cycloaddition of butyltin azide with substituted alkynes followed by a N-alkylation reaction. The regioisomers have been isolated and characterized using NMR tec

A cycloaddition route to novel triazole boronic esters

The [3 + 2] cycloaddition of alkynylboronates and azides provides a direct route to novel triazole boronic esters, the regioselectivity of this process and functionalisation of the heterocycle products is described. The Royal Society of Chemistry.

1,2,3-Triazole derivatives as cannabinoid-receptor modulators

The invention relates to the use of compounds having pharmacological activity towards the so-called cannabonid receptors, and more particularly to some 1,2,3-triazole derivatives of formula (I): to processes of preparation of such compounds and to pharmac
