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。
