Discovered concurrently by Meldal and Sharpless in 2002, 1,2 CuAAC has become popular in the scientific community and is the most widely used ‘click’-type 3 reaction. 4–6 CuAAC is a Huisgen 1,3-dipolar cycloaddition between organic azides and terminal alkynes, catalyzed by a copper (I) species (see Scheme 1 ).The compound, which we’re going to call azidoazide azide – more on that later – is made up of two carbon atoms, no hydrogen, and a staggering fourteen nitrogen atoms, making it 89.1% nitrogen by weight and one of the most nitrogen-rich organic compounds ever made. From that description alone, most chemists are going to start wincing.The diversity of nucleic acid sequences enables genomics studies in a highly multiplexed format.
