Importantly, the diversity of these highly complex compounds and libraries of {HEAD ~ compounds} reminiscent of natural products, as discussed above, results both from the ability to diversify the templates and combinatorializable units used to synthesize the scaffold structures, and from {TAIL ~ the diversity} generated upon reaction with the latent and non latent functionalities in the scaffold structure
