摘要：

The title compounds 4 were prepared via Diels-Alder reaction of 3,5-dichloro-2(1H)-pyrazinones 1 with ethene, followed by catalytic reduction of the iminochloride group generated in the cycloadducts 2. Substitution of the iminochloride group with various nucleophiles afforded the 6-functionalised analogues of 2. Their reduction can lead to 6-substituted derivatives of compounds 4. One example is given.
