Azides and acetylenes are bio-orthogonal functional groups that can be readily coupled using copper(I)- or ruthenium(II)- catalyzed 1,3-dipolar cycloaddition reactions. Using non-fluorescent aromatic azides and aromatic acetylenes, covering a range of electron rich and poor building blocks, the Huisgen cycloaddition afford 1,4-disubstituted or 1,5-disubstituted 1,2,3-triazoles. Using a combinatorial approach by running reaction in parallel in polypropylene 96-well plates we discovered several new fluorescent 1,2,3-triazoles scaffolds. These compounds show diverse interactions with biomolecules that could find applications in biology in, for example, fluorescence microscopy or biomolecule quantification.

A new series of mollugin-1,2,3-triazole derivatives were synthesized using a copper(I)-catalyzed Huisgen 1,3-dipolar cycloaddition reaction of corresponding O-propargylated mollugin with aryl azides. All the compounds were evaluated for their cytotoxicity on five human cancer cell lines (HL-60, A549, SMMC-7721, SW480, and MCF-7) using MTS assays. Among the synthesized series, most of them showed cytotoxicity and most of all, compounds 14 and 17 exhibited significant cytotoxicity of all five cancer cell lines.

(Chemical Equation Presented) A panel of small molecule-based MMP inhibitors containing rhodanine warheads was assembled using "one-pot" click chemistry. Upon biological screening, moderate inhibitors were identified which specifically targets MMP-7 and MMP-13 over other MMPs.

A novel hypervalent iodine induced nucleophilic substitution of para-substituted phenol ethers in the presence of a variety of nucleophiles is described. UV and ESR spectroscopic studies indicate that this reaction proceeds via cation radicals, [ArH?+], as reactive intermediates generated by single-electron transfer (SET) from a charge-transfer (CT) complex of phenol ethers with phenyliodine(III) bis(trifluoroacetate) (PIFA). This is the first case that involves a radical intermediate on hypervalent iodine oxidations of aromatic compounds.

A novel and useful method for the azidation of aromatic compounds by the reaction of hypervalent iodine reagent, phenyliodine(III) bis(trifluoroacetate) (PIFA) in 1,1,1,3,3,3-hexafluoro-2-propanol followed by treatment of trimethylsilyl azide (TMSA) was developed. The possible mechanism is also discussed.
