  Investigations into a mild Diels-Alder approach to 6-substituted quinazoline-2,4-dione derivatives

  摘要：

  Furo[3,4-d]pyrimidine-2,4-dione (2) has been reacted with a number of dienophiles to give the Diels-Alder adducts such as 3 and 4 under very mild reaction conditions. Methyl acrylate gives only two regioisomeric endo products which have been isolated and characterized. Other dienophiles give mixtures of endo and exo products as well as of regioisomers. The product ratios were determined by high field H-1 NMR analysis. These adducts are dehydrated by treatment with acid to form some novel quinazoline-2,4-dione derivatives.
