AbstractCommercially available p-aminobenzoic acid was used as a precursor for the synthesis of novel fused, non-fused, and spiro polyheterocyclic derivatives bearing indene, imidazole, pyrazole, and/or triazine nucleus via addition to simple and accessible reagents such as ninhydrin, o-phenylenediamine, and carbon disulfide. The experimental procedures were straightforward and simple, the products
摘要可商购的p氨基苯甲酸被用作新颖的稠合的合成的前体,非稠合,螺环和多杂环衍生物轴承茚,咪唑,吡唑,和/或经由除了简单和方便的试剂如茚三酮,三嗪核ö -苯二胺和二硫化碳。实验步骤简单明了,分离出的产品收率为15–86%,并且。通过光谱数据证实了它们的结构。评价合成的化合物对某些革兰氏阳性和革兰氏阴性细菌的抗菌活性。
