A new series of nine derivatives of 4H‐pyrano[3,2‐c]chromene and 12 derivatives of N‐thiazolyl‐4H‐quinoline of 1H‐pyrazole has been synthesized by one pot base catalyzed cyclocondensation reaction of 1H‐pyrazole‐4‐carbaldehyde, malononitrile, and 4‐hydroxy coumarin or β‐enaminones, respectively. All the synthesized compounds were characterized by elemental analysis, FT‐IR, 1H NMR, 13C NMR spectral
一个新的系列的第4 9个衍生物的ħ吡喃并[3,2- c ^ ]色和12个衍生物Ñ噻唑基-4- ħ -喹啉的1个ħ吡唑已由1的一锅碱催化环化缩合反应合成ħ -分别为吡唑-4-甲醛,丙二腈和4-羟基香豆素或β-烯胺酮。通过元素分析,FT-IR,1 H NMR,13 C NMR光谱数据对所有合成的化合物进行表征,然后针对一组致病性细菌和真菌菌株进一步筛选。
