Abstract

Pyridazines were allowed to react with allyltributyltin in the presence of chloroformate to give 1-alkoxycarbonyl-6-allyl- and 1-alkoxycarbonyl-4-allyldihydro-pyridazines as major and minor products, respectively. The reaction was applied to other diazines, and tetrahydro-adducts were obtained in the case of pyrimidine and pyrazine. Benzo-fused diazines also reacted in the same manner to afford the allyl-adducts in good yields.
