The o-nitrobenzyl group, possessing distinct advantage of being photolabile under mild conditions, was successfully connected to 8-(5,6-epoxynorbornan-2-yl)-1,3-dipropylxanthine (5), a high specific A1 adenosine receptor antagonist. The resulting compound 4 would have potential use as a prodrug.

This report describes the behavior of four 1-amino-2-phenyl-1-cyclohexanecarboxylic acids, obtained in enantiomerically pure form starting from asymmetric Diels-Alder reactions between 1,3-butadiene and chiral (E)-2-cyanocinnamates, as chiral auxiliaries in the asymmetric Diels-Alder reactions of cyclopentadiene with chiral methyl N-acryloyl-1-amino-2-phenyl-1-cyclohexane-carboxylates. A model based on the formation of an intramolecular hydrogen bond accounts for the stereochemical outcome in the catalyzed reactions.
