Epimeric spirohydantoins of glucofuranose, analogues of hydantocidin, are readily prepared from glucoheptonolactone. No rearrangement of spirohydantoins of glucofuranose to pyranose isomers was observed; a novel rearrangement was observed of a glucofuranose spirohydantoin to an isomeric oxazolidinone, (3aR,4′R,5S,6S,6aR)-5-(2′,2′-dimethyl-1′,3′-dioxolane-4′-yl)-6-hydroxy-3a-N-phenylcarboxamido-tetrahydrofuro
葡糖呋喃糖的差向异构螺乙内酰脲(hydantocidin的类似物)很容易从葡庚糖内酯制备。没有观察到葡糖呋喃糖的螺旋乙内酰脲重排为吡喃糖异构体;观察到呋喃葡萄糖spirohydantoin的一种同分异构体的恶唑烷酮的新颖重排,(3 AR,4' - [R,5小号,6小号,6 AR)-5-(2',2'-二甲基-1',3'-二氧戊环-4′-基)-6-羟基-3a-N-苯基羧酰胺基-四氢呋喃[2.3-d] -1,2-恶唑烷-2-one,其结构通过X射线晶体学分析确定。(1'R,2 R,3 R,4 R,5 R的X射线晶体结构报道了)-6,8-二氮杂-3,4-二羟基-2-(1′,2′-二羟乙基)-1-氧杂-8-N-苯基-螺环[4.4]壬烷-7,9-二酮。
