Resumo:
The present work is part of a larger project aimed at obtaining compounds of industrial interest from renewable sources. The work is particularly aimed to investigate the reactivity of 2,5-bis-hydroxymethylfuran (BHMF), an important building block of organic nature easily obtainable from biomass, with acid catalysis. Through the study of the reactivity of BHMF in water, in the presence of an heterogeneous acid catalyst (Amberlyst 15), has been developed a new synthetic method for the preparation of α-6-hydroxy-6-methyl-4-enyl-2H-pyran-3-one a derivative whose molecular skeleton is similar to that of natural products which are used in pharmaceutical chemistry. The product is obtained in milder conditions and with better selectivity with respect to the strongly oxidizing conditions with which it is prepared in the literature starting from different precursors containing furan ring.
