The invention describes new spiro[chroman-2,2'-indole] derivatives of formula (I). When compounds of the invention, 1',3',3,4-tetrahydrospiro[chromen-2,2'-indoles], are treated with solution containing cyanide ions, 3,4-dihydropyrane ring opening occurs, resulting in formation of colored 4-nitrophenolate ion, which is detectable colorimetrically.
该发明描述了公式(I)的新的spiro [chroman-2,2'-indole]衍生物。当使用含氰离子的溶液处理本发明的化合物1',3',3,4-四氢spiro [chromen-2,2'-indoles]时,会发生3,4-二氢吡喃环的开放,形成有色的4-硝基苯酚离子,可通过比色法检测到。
