and chalcones with ethyl isocyanoacetate afforded 3,4-diaryl- and 4-acyl-3-arylpyrroles, respectively. 3-Arylpyrrole-2,4- dicarboxylates and 4-arylisoxazoline N-oxides were side reaction products. Antimitotic activity of target 3,4-disubstituted pyrroles was studied on a sea urchin embryo model. Pyrroles unsubstituted at positions 2 and 5 were the most active. The activity increased with the number of
硝基取代的芪和查耳酮与异氰乙酸乙酯的 Barton-Zard 反应分别得到 3,4-二芳基-和 4-酰基-3-芳基吡咯。3-芳基吡咯-2,4-二羧酸酯和4-芳基异恶唑啉N-氧化物是副反应产物。在海胆胚胎模型上研究了目标 3,4-二取代吡咯的抗有丝分裂活性。在位置 2 和 5 未被取代的吡咯是最活跃的。活性随着 Ar 取代基中甲氧基的数量增加而增加。
