A series of spiro hydantoins derivedfrom 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)。

(EN) A series of novel $i(spiro)-heteroazolones derived form a 2,3-dihydropyrano[2,3-b]pyridine ring system have been prepared, including their pharmaceutically acceptable salts. These compounds are useful in therapy as aldose reductase inhibitors for the control of certain chronic diabetic complications. Typical member compounds include $i(spiro)-imides, $i(spiro)-oxazolidinediones, $i(spiro)-thiazolidinediones and $i(spiro)-imidazolidinediones derived from the aforesaid ring system. (4'$i(S)) (2'$i(R))-6'-chloro-2',3'-dihydro-2'-methyl-$i(spiro)-[imidazolidine-4,4'-4'H-pyrano[2,3-b]pyridine]-2,5-dione represents a typical and preferred member compound. Methods for preparing all these compounds from known starting materials are provided.(FR) Une série de nouvelles $i(spiro)-hétéroazolones dérivées d'un système cyclique 2,3-dihydropyrano[2,3-b]pyridine ont été préparées, y compris leurs sels pharmaceutiquement acceptables.
