Abstract
The Diels-Alder reaction of cyclopentadiene with eight electron defici ent dienophiles was studied. The reaction was performed at room temper ature using silica gel as an inorganic support, without solvent. Only one of the two possible Diels-Alder adducts was isolated in moderate t o good yield. The structure of products with endo-oriented electron-wi thdrawing group was proved by H-1 NMR spectrum and in one case (9b) by X-ray analysis.
