Abstract
The adducts of cyclopentadiene and azodicarboxylate esters were treated with benzenesulphonyl azide producing the fused aziridine derivatives, (4) and (5); hydrolysis of the ethyl ester (4) gave the diazatricylene (7) whereas hydrolysis of the t-butyl ester led to the dihydropyridine (9).Keywords
