                                Cycloadducts of ethene with 2(1H)-pyrazinones and their conversion into 2,5-diazabicyclo[2.2.2]octane-3,6-diones.

                                Cycloaddition of variously substituted 2(1H)-pyrazinones with ethene and subsequent hydrolysis of the adducts 2 provides a general and efficient route to the title compounds 3.  Compound 3m was used as a building block for a structural analogue of gliotoxin.
