chloroform to give the spiro[oxolane-2,2′-piperazine]-3′,6′-dione derivative. The spiro compound was further treated with NBS in water to give the corresponding spiro[oxolane-2,2′-piperazine]-3′,5′,6′-trione and -3′,6′-dione-5′-ol. The latter compound and a new spiro-5′,6′-dione-3′-ol derivative were also obtained by the reduction of the spiro-3′,5′,6′-trione. The structural confirmation of all the new
将衍生自 4-乙氧基羰基-2-氯乙酰氨基-2-丁烯酸乙酯的化合物 3-(3-羟基) 亚丙基-哌嗪-2,5-二酮在氯仿中用 N-溴代琥珀酰亚胺 (NBS) 处理得到螺[ oxolane-2,2'-piperazine]-3',6'-dione 衍生物。螺化合物进一步用NBS在水中处理,得到相应的螺[oxolane-2,2'-piperazine]-3',5',6'-trione和-3',6'-dione-5'-ol . 后一种化合物和新的spiro-5',6'-dione-3'-ol衍生物也通过spiro-3',5',6'-trione的还原得到。讨论了所有新产品的结构确认。
