  Reactions of 7-substituted 1, 3, 9-trimethyl-8, 9-dihydroxanthines (3) with dimethyl acetylenedicarboxylate afforded heteropropellanes (5) in good yields. The reactions with methyl propiolate afforded pyrimidodiazepines (7) as well as propellanes (6) when the xanthines have small substituents at the 7 position. The mechanisms of formation of the products are also discussed.

  The novel ring transformation reactions were found in the reactions of 1,3,7,9-tetra-alkyl-8,9-dihydroxanthines and acetylenic compounds. The reaction of the dihydroxanthine with DMAD gave a propellane type compound and with methyl propiolate afforded the similar type compound and a pyrimido[4,5-b]diazepine derivative. The mechanism of these reactions was also discussed.

  在1,3,7,9-四烷基-8,9-二氢黄嘌呤与炔属化合物的反应中发现了新的环转化反应。二氢黄嘌呤与DMAD的反应得到了丙炔型化合物，并且与丙炔酸甲酯得到了类似的化合物和嘧啶基[4，5-b]二氮杂卓衍生物。还讨论了这些反应的机理。
