A series of spiro hydantoins derived from 8-azachromanones (2,3-dihydro-4H-pyrano[2,3-b]pyridin-4-ones) has been prepared and tested for aldose reductase inhibitory activity. The standard Bucherer-Bergs conditions had to be drastically modified to increase yields from less than 1% to an acceptable 50% range. One of the most potent compounds was cis-6'-chloro-2',3'-dihydro-2'-methylspiro[imidazolidine-4
制备了一系列衍生自8-氮杂苯并二氢吡喃酮(2,3-二氢-4H-吡喃并[2,3-b]吡啶-4-酮的螺旋乙内酰脲)的醛糖还原酶抑制活性。必须对Bucherer-Bergs标准条件进行彻底修改,以将收率从不到1%提高到可接受的50%范围。最有效的化合物之一是cis-6'-chloro-2',3'-dihydro-2'-methylspiro [imidazolidine-4,4'-4'H-pyrano [2,3-b] pyridine] -2 ,5-二酮; 该化合物的拆分结果表明2'R,4'S对映异构体16是该系列中活性最高的螺乙内酰脲,对人胎盘醛糖还原酶的IC50为7.5 x 10(-9)。
