decarbonylation of methyl 1-aryl-3-(het)aroyl-4,5-dioxo-4,5-dihydro-1H-pyrrole-2-carboxylates afforded 8-substituted methyl 3-(het)aroyl-4-oxo-1,4-dihydroquinoline-2-carboxylates. X-ray diffraction studies revealed no hydrogen bonds in the crystals of the compounds obtained. According to spectral data, hydrogen bonding is possible in concentrated solutions of 8-substituted methyl 4-oxo-1,4-dihydroq
1-芳基-3-(het)aroyl-4,5-dioxo-4,5-dihydro-1H-pyrrole-2-carboxylates 甲基的热脱羰得到 8-取代的甲基 3-(het)aroyl-4-oxo- 1,4-二氢喹啉-2-羧酸盐。X 射线衍射研究表明在所得化合物的晶体中没有氢键。根据光谱数据,在 8-取代的 4-氧代-1,4-二氢喹啉-2-羧酸甲酯的浓溶液中可能存在氢键。
