ABSTRACT
        Environmental aspects have developed a novel part of chemistry called Sustainable Chemistry. The most important objective is prevent and decrease the pollution as much on industrial scale as in research laboratories. In this aspect, heterogeneous catalysis can allow an easy and safe handing of reaction, as well as, a good separation, recovery and possibility of regeneration. As a result, heterogeneous catalysis contributes to the absence of polluting spills with the consequence environmental respect.
      The polifuncionality and the possible presence of heteroatoms in the structure of the fine chemical products make more difficult the application of the heterogeneous catalysts, however, most of them are used in petrochemical industry.
      In the present thesis, have been described the several possibilities offered by different heterogeneous catalysts for the obtaining of Fine Chemical products like fragrances, food additives and drugs.
      It has been detailed the synthesis of the following high added value products using heterogeneous catalytic systems:
       	Interesting molecules from an industrial point of view have been synthesized like melon fragance and d-Decalactone, which has a creamy coconut and peach-like aroma and is an important constituent of many dairy products, using the oxidation system Sn-Beta/H2O2. This alternative system produces only water as subproduct instead of the great amount of by-products that are generated with the classic synthesis.
         	Solids with basic character, have been used as an alternative of sodium hydroxide solutions, to carry out the transesterificación reaction between fatty acid methyl esters and poliethylenglicol, in this way, they have avoided the problems derived from the use of homogenous catalysts as for exemple the reactors corrosion, the catalyst neutralization after reaction and the impossibility to be reused. The resulting esters are interesting by their surfactants properties, being able to be used even, in the food industry by the absence of toxicity.
       	A new synthetic route for the production of Nabumetone drug, an anti-inflammatory non steroidal, have been described. This new method combines two reactions in a cascade process: aldolic condensation and hydrogenation, using trifunctional catalytic system with acid, basic and metal centers. In this way is possible to obtain a yield of 98% after 1h of reaction.
       	Finally, the synthesis raspberry fragance, has also been obtained by means of an alternative synthesis. This consists of the one pot reaction of Heck coupling followed by a hydrogenation using as catalytist Pd supported on different metallic oxides.
