Stereoselective hydrogenation of methylcyclohex-2-ene-1,4-diols used as important intermediates for the preparation of ampelomins and deoxy-carbasugars was studied. These olefins were obtained in few steps from a chiral cis-diol resulting from microbial oxidation of toluene. Although the stereoselective hydrogenation of this type of substrates is difficult, high yields were obtained for heterogeneous...
Nowadays, new strategies for pest and disease control to be used in rotation with or replacement of conventional pesticides are required. Essential oils (EOs), as botanical pesticides, provide a potential resource to develop more environmentally friendly and less toxic means of control to be applied in different produces.
