CuAAC-inspired synthesis of 1,2,3-triazole-bridged porphyrin conjugates: an overview

open access: yesBeilstein Journal of Organic Chemistry, 2023
Among all the available approaches in organic synthesis, the “click chemistry” protocol is very common nowadays to covalently connect two diverse moieties in a single framework. Therefore, this review focuses on the synthesis and photophysical studies of

A Genetically Encoded Picolyl Azide for Improved Live Cell Copper Click Labeling

open access: yesFrontiers in Chemistry, 2021
Bioorthogonal chemistry allows rapid and highly selective reactivity in biological environments. The copper-catalyzed azide–alkyne cycloaddition (CuAAC) is a classic bioorthogonal reaction routinely used to modify azides or alkynes that have been ...

Synthesis and CuAAC Reactions of Azidoalkylethoxysilanes: Grafting CuAAC Products onto Silica Surface [PDF]

open access: yesSynthetic Communications, 2013
One-pot synthetic protocols of novel azido functionalized silane coupling agents from corresponding terminal mesylated or tosylated 1-olefins were developed. Azido groups were successfully converted to the corresponding 1,2,3-triazol ring by the copper-catalyzed azido alkyne coupling (CuAAC) reaction without alkoxysilane decomposition.
