Direct synthesis of condensed triazoles from diverse sulfamidates by ring opening of sulfamidates with sodium azide followed by one-pot propargylation and cycloaddition furnished title compounds. The methodology in general has been demonstrated on diverse sulfamidates derived from amino acids, amino acid derivatives, and carbohydrates to obtain diverse triazole fused scaffolds. In one example, a condensed
通过用叠氮化钠使氨基磺酸盐开环,然后进行一锅炔丙基化和环加成反应制得标题化合物,由多种氨基磺酸盐直接合成缩合三唑。一般而言,该方法论已在衍生自氨基酸,氨基酸衍生物和碳水化合物的多种氨基磺酸盐上得到了证明,从而获得了多种由三唑稠合而成的支架。在一个实例中,已经通过使磺酰胺酯衍生物与炔丙基胺开环合成了含氨基酸的稠合三唑。
