The overall research proposal encompass three distinct projects focusing on the methodological, mechanistic, and synthetic aspects of Heck arylations employing arenediazonium salts, the so-called Heck-Matsuda reaction.The first project explores the Heck-Matsuda reaction on substrates which can perform as complexing substrates to the palladium catalyst. This project gives continuity to a well-succeeded project initiated recently in the lab dealing with allylic alcohols. In this new proposal we plan to use substrates such as allylamides, allyl carbamates, allyl malonates and some new allylester derivatives. This type of method is new in the literature - our first publications appearing in 2011 - and demonstrates a high synthetic potential to produce important compound (bioactive compounds, for example) in a regio- and stereocontrolled manner. These are well regarded qualities in a synthetic route.Project 2 deals with the synthesis of new fluorescent probes starting from the Heck-Matsuda reaction. These fluorescent probes constitutes novel compounds and demonstrate an exceptional potential as fluorescent markers of use in Biochemistry and/or Chemical Biology, thus allowing to follow biological processes in a precise way in real time.Project 3 is intended to apply the Heck arylation processes with a more medicinal focus, thus providing new analogues of a family of antitumor compounds known as combretastatins. This new approach to the synthesis of these important compounds poses as an efficient one which can be carried out in a few steps. The more adequate starting material for such an enterprise will be evaluated from dimethyl fumarate and dimethyl acetylenedicarboxylate, and should complement in some way the traditional maleic anhydride used for the first generation of this project.
