چکیده
The synthesis and kinetic resolution of quaternary oxindoles through copper catalysed azide-alkyne cycloadditions is presented. Selectivity factors (s) up to 22.1 ± 0.5 are reported. Enantioenriched alkynes and triazoles were obtained in ≥80% enantiomeric excess (e.e.).

Enantioselective synthesis of C-linked spiroacetal-triazoles as privileged natural product-like scaffolds.
The enantioselective synthesis of novel C-linked spiroacetal-triazoles 10 is reported. The key step involves reaction of acetylenic spiroacetal 11 with several azides by the Copper-Catalysed Azide-Alkyne Cycloaddition (CuAAC). The biologically privileged spiroacetal scaffold 11 was prepared from silyl-protected Weinreb amide 19 using several reliable Grignard additions and a highly diastereosel...
متن کاملStructural Determinants of Alkyne Reactivity in Copper-Catalyzed Azide-Alkyne Cycloadditions.
This work represents our initial effort in identifying azide/alkyne pairs for optimal reactivity in copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions. In previous works, we have identified chelating azides, in particular 2-picolyl azide, as "privileged" azide substrates with high CuAAC reactivity. In the current work, two types of alkynes are shown to undergo rapid CuAAC reactions u...
متن کاملCopper catalysed azide-alkyne cycloaddition (CuAAC) in liquid ammonia.
Copper(I) catalysed azide-alkyne cycloaddition reactions (CuAAC) occur smoothly in liquid ammonia (LNH(3)) at room temperature to give exclusively 1,4-substituted 1,2,3-triazoles with excellent yields (up to 99%). The CuAAC reactions in liquid ammonia require relatively small amounts of copper(I) catalyst (0.5 mole%) compared with that in conventional solvents. The product can be obtained conve...
متن کاملSynthesis and Characterization of Isomeric Vinyl-1,2,3-triazole Materials by Azide-Alkyne Click Chemistry
The synthesis of isomeric, functionalized 4-vinyl-1,2,3-triazole and 5-vinyl-1,2,3-triazole monomers is demonstrated using heterogeneous copper (copper-in-charcoal)-catalyzed azide-alkyne cycloaddition (CuAAC) or homogeneous ruthenium (Ru)-catalyzed azide-alkyne cycloadditions (RuAAC) “click” protocols. These reactions are regiospecific, exclusively forming 1,4and 1,5-disubstituted triazoles as...
متن کاملAccess to functionalised silver(I) and gold(I) N-heterocyclic carbenes by [2 + 3] dipolar cycloadditions.
A new strategy was developed for the modification of silver(I) and gold(I) N-heterocyclic carbenes. Azido groups were grafted and used either by copper-catalysed azide-alkyne cycloaddition before metallation or by thermal and "strain-promoted" 1,3-dipolar cycloaddition after metallation to functionalise the metal-NHCs.
