Expanding cyclitol structural diversity by biocatalysis and metalocatalysis. A click chemistry approach
The palladium catalyzed cross-coupling reaction of phenyltrifluoroborate with a chemoenzymatically derived bromoazidoconduritol, combined with 1,3-dipolar cycloaddition, with a variety of alkynes is described. Fourteen new ...
Coupling biocatalysis and click chemistry: one-pot two-step convergent synthesis of enantioenriched 1,2,3-triazole-derived diols
(Royal Society of Chemistry, 2013-02)
A fully convergent one-pot two-step synthesis of different chiral 1,2,3-triazole-derived diols in high yields and excellent enantio- and diastereoselectivities has been achieved under very mild conditions in aqueous medium ...
Click chemistry decoration of amino sterols as promising strategy to developed new leishmanicidal drugs.
(Elsevier Science Inc, 2014-01)
A series of 1,2,3-triazolylsterols was prepared from pregnenolone through reductive amination and copper(I)-catalyzed azide-alkyne cycloaddition (click chemistry). The newly generated stereocenter of the key propargylamino ...
Synthesis of 1,2,3-triazolylpyranosides through click chemistry reaction
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
We have developed an efficient method for the synthesis of functionalized C-glycosyl 1,2,3-triazoles through a Cu(1)-promoted azide-alkyne 1,3-dipolar cycloaddition between a TMS-protected C-alkynyl-glycoside and organic ...
Application of copper(I)-catalysed azide/alkyne cycloaddition (CuAAC) `click chemistry` in carbohydrate drug and neoglycopolymer synthesis

Preparation of bifunctional mesoporous silica nanoparticles by orthogonal click reactions and their application in cooperative catalysis
(Wiley-VCH VerlagWeinheim, 2012-12)
The synthesis of bifunctional mesoporous silica nanoparticles is described. Two chemically orthogonal functionalities are incorporated into mesoporous silica by co-condensation of tetraethoxysilane with two orthogonally ...
Palladium Nanoparticles Embedded in a Layer-by-Layer Nanoreactor Built with Poly(Acrylic Acid) Using "electro-Click Chemistry"
(American Chemical Society, 2016-07)
Palladium nanoparticles (Pd NPs) were formed by electrochemical reduction of Pd(NH3)43+ ions entrapped by ion exchange in poly(acrylic acid) (PAA) multilayer films grown by the Sharpless "click reaction." The alkyne (PAAalk) ...
Simple thiol-ene click chemistry modification of SBA-15 silica pores with carboxylic acids
(Academic Press Inc Elsevier Science, 2015-07)
A straightforward approach for anchoring tailored carboxylic groups in mesoporous SiO2 colloidal materials is presented. The thiol-ene photochemical reaction between vinyltrimethoxysilane precursors and various thiocarboxylic ...
