In this preliminary study, it was shown that strong acid ion exchange resins allowed the dehydration of D-fructose to 5-hydroxymethyl-2-furancarboxaldehyde at mild temperatures and pressures. Evidence was given that the use of a solvent (i.e. methyl

The use of ion-exchange resins for the esterification of furoic acid and 5-nitrofuroic acid was characterised by an excellent yield and the absence of side reactions, particularly when the reaction was carried out in cyclohexane in the presence of th

Carbonylation of (1 R ,4 R )-isolimonene, catalyzed by [HPd(SnCl 3 )(dppf)], involves the exo - and endo -carboncarbon double bonds to provide a cyclopentanone containing two new stereogenic centers with d.e. of 69%. It was shown that this diaster
