  摘要：

  1-氯苄异氰酸酯与S,N-和N,N-硝基烯酰基的环缩合反应被用来合成迄今为止未知的6-硫甲基-5-硝基-3,4-二氢嘧啶-2(1H)-酮、8-硝基-2,3,6,7-四氢咪唑[1,2-c]嘧啶-5(1H)-酮以及9-硝基-1,2,3,4,7,8-六氢-6H-吡咯[1,6-a]嘧啶-6(1H)-酮。对6-硫甲基-5-硝基-3,4-二氢嘧啶-2(1H)-酮中硫甲基的取代生成6-氨基-5-硝基-3,4-二氢嘧啶-2(1H)-酮，该化合物与4-亚氨基-5-硝基-3,4,5,6-四氢嘧啶-2(1H)-酮存在互变异构平衡。如果将所获得的化合物在1,8-二氮双环[5.4.0]十一烯（DBU）存在下于二噁烷中加热，会消除硝基生成取代的4-亚氨基-3,4-二氢嘧啶-2(1H)-酮。

  1-Chlorobenzyl isocyanates react with N-arylfumarates with the formation of dialkyl 2-oxo-3,6-diaryl-1,2,3,6-tetrahydropyrimidine-4,5-dicarboxylates that on alkaline hydrolysis are converted into 6-alkoxycarbonyl-1,4-diaryl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acids. The condensation of 1-chloro-1-phenyl-2,2,2-trifluoroethyl isocyanate with N-arylfumarates results in dialkyl 6-oxo-2,3-diaryl-2-trifluoromethyl-1,2,3,6-tetrahydropyrimidine-4,5-dicarboxylates.

  A new convenient approach to the synthesis of N1-sub-stituted 3,4-dihydropyrimidin-2(1H)-ones was developed using the regioselective cyclocondensation of α-chlorobenzyl isocyanates with ethyl N-alkyl(aryl)-β-aminocrotonates. A number of Nl-aryl and N1-alkyl substituted Biginelli compounds difficult to obtain by other methods were prepared with high yields.

  The cyclocondensation of 1-chlorobenzyl isocyanates with S,N- and N,N-nitroketeneacetals has been employed to synthesize hitherto-unknown 6-methylthio-5-nitro-3,4-dihydropyrimidin-2(1H)-ones, 8-nitro-2,3,6,7-tetrahydroimidazo[1,2-c]pyrimidin-5(1H)-ones and 9-nitro-1,2,3,4,7,8-hexahydro-6H-pyrimido[1,6-a]pyrimidin-6(1H)-ones. Substitution of the methylthio group in 6-methylthio-5-nitro-3,4-dihydropyrimidin-2(1H)-ones provided 6-amino-5-nitro-3,4-dihydropyrimidin-2(1H)-ones, which exist in tautomeric equilibrium with 4-imino-5-nitro-3,4,5,6-tetrahydropyrimidin-2(1H)-ones. The compounds obtained, if boiled in dioxane in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), eliminate the nitro groups to give substituted 4-imino-3,4-dihydropyrimidin-2(1H)-ones.
