Click Chemistry 'CC' are Cu(I) catalyzed 1,3-dipolar 3]2] cycloaddition between azides and alkynes CuAAC]. The versatility of CuAAC or 'click reaction' seem endless with the discovery and invention of new chemical transformations which meet 'click' status, the future looks bright for CC. Recently, Click chemistry has received considerable attention as powerful modular synthesis approach, which has found numerous applications in many areas of modern organic chemistry, drug discovery, radiopharmaceutical sciences and material science. The great success of CC encouraged researchers to develop...
