This has allowed to study keto-enol tautomerism in these systems and assess theway in which the presence of acyloxy or aminoacyl groups bound to the C2 position affects suchtautomerism, and to investigate the reactivity of both the enol and carbonyl forms. In this work wealso prove the versatility of the Passerini reaction, since depending on the conditions to which thecorresponding adducts are subjected different products of synthetic interest can be obtained.
