Total Oxidation under Thermal Activation Conditions

Total Oxidation under Thermal Activation Conditions 

Strictly related to diesel exhausts, hterature mentioned about 50 hydrocarbons representing heavy hydrocarbons. They were classified into three groups alkanes and isoalkanes, alkenes and isoalkenes, and aromatics (mono-and polycyclic hydrocarbons) and oxygenated derivatives [19].

Dienes 19 and 20 only react with A-phenylmaleimide (21) when the reactions are activated by high pressure cycloadditions with the more reactive dienophile 1 also occur under thermal conditions, but in lower yield. The reactions are totally a ft-(with respect to the unsubstituted benzene ring of the para-cyclophane unit ) enc/o-diastereoselective. DDQ oxidation of cycloadduct 24 led to the aromatized compound 26 while the aromatization of 23 and 25 failed. Interestingly, the cycloaddition between 1 and 19 led to the aromatized compound 22 this clearly indicates that 1,4-benzoquinone also acts as an oxidant.
