Due to their importance and versatility demonstrated in the recent years, organometallic bases have been widely employed in the preparation of many functionalized aromatic and heteroaromatic rings. Among of six membered heterocyclic compounds, quinazolines and quinazolinones occupy a central position and their structures are commonly found in several molecules presenting biological activities such as anti-inflammatory, antioxidant, antimicrobial, antihypertensive, anticancer, among others. Thus, in this project our main objective is to investigate the applicability of the mixed amides of magnesium-lithium (TMPMgCl*LiCl and TMP2Mg*2LiCl) and zinc-lithium (TMPZnCl*LiCl) in the fuctionalization of quinazolinic derivatives aiming the preparation of bioactive molecules. As an alternative for the metallation reactions, we also intend to study the functionalization of halogenated quinazolines by the reaction of halogen-metal exchange using i-PrMgCl*LiCl (turbo-Grignard).Moreover, aiming to demonstrate the importance of the developed synthetic methodologies, they will be applied to the synthesis of Verubulin and its analogues with basic structure of 4-aminoquinazolines, which are found in a number of drugs with anticancer activity. Finally, the reactions exhibiting the most promising results will be investigated under continuous flow conditions to evaluate the potential of this technique in scaling up processes. (AU)
