2,3-Dihalofenolessustratos de partida versátiles para la síntesis de heterociclos funcionalizados regioselectivamente

Abstract

This Thesis has been focused on the preparation of different functionalized heterocycles that show considerable importance in Organic Chemistry because they constitute the core of a wide variety of compounds with biological or pharmacological properties. In this field, we have developed efficient routes to the synthesis of regioselectively functionalized indoles, benzo[b]furans and benzo[b]thiophenes. The directed ortho-metalation strategy in conjunction with palladium-catalyzed cross-coupling reactions have been mainly used to achieve this goal. The potential of these synthetic routes is that they allow an easy access to a wide variety of interesting products in a regioselective way by employing commercially or easily available starting materials. In addition, these strategies generally involve an improvement in relation to existing methodologies due to their selectivity and simplicity.
