Cycloadditions between (+)-nopadiene and 2-cyclopenten-1-one, 2-cyclohexen-1-one, 4-oxo-2-cyclopentenyl-acetate and two indenone derivatives, prepared in situ from the corresponding bromoindanones, have been studied. All cycloadditions are regioselective and endo-anti diastereoselective. The best yields were obtained when the Diels-Alder reactions were carried out under high pressure conditions. All new compounds were characterized by their spectroscopic data, in particular by extensive NMR investigations

Abstract
Cycloadditions between (+)-nopadiene and 2-cyclopenten-1-one, 2-cyclohexen-1-one, 4-oxo-2-cyclopentenyl-acetate and two indenone derivatives, prepared in situ from the corresponding bromoindanones, have been studied. All cycloadditions are regioselective and endo-anti diastereoselective. The best yields were obtained when the Diels-Alder reactions were carried out under high pressure conditions. All new compounds were characterized by their spectroscopic data, in particular by extensive NMR investigationsFile in questo prodotto:
