New triazole linked conjugates were obtained from protoescigenin monopropargyl ethers and sugar azides, under Cu(II) salt promotion in good yield, without losing isopropylidene protection.

Aromatic aldehydes have been converted into the corresponding carbamoyl azides using iodine azide. These reactions have been performed safely under continuous flow reaction conditions in microreactors.

Dextrans modified with alkyne and azide groups through hydrolysable carbonate esters form degradable microcapsules after Cu(I) catalysed 'click' reaction between azides and alkynes yielding triazole cross-links.

A three-component reaction of indoles, sulfonyl azides and terminal alkynes afforded 3-functionalized indoles in a single step via copper-cascade catalysis.

A series of sugar-derived spiroaminals has been synthesized by utilizing cross metathesis, ring closing metathesis and lactamization reactions as key steps from 1-C-alkylated glycosyl azides and important correlations in the spectral data between spiroaminals and their respective anomers are reported.

We have demonstrated that iron porpholactones could be effective catalysts for nitrogen atom transfer reactions such as aziridination of alkenes and amidation of alkanes using organic azides.

A latent catalyst for the [3+2] cycloaddition reaction of azides and alkynes has been developed in accordance with the principles of Click chemistry.
