nitromethane resulted in the formation of glycopyranosylidene-spirohydantoins 3, 11 and 15 and -thiohydantoins 7 and 16. Zemplén-deacetylation gave the pyranoid epi-hydantocidin analogues 4 and 12, and thiohydantocidin analogues 8 and 17, respectively.
TiCl 4介导的乙酰化1-溴-甘露糖基氰基氰化物1和9中腈部分的部分水解得到C-(1-溴-1-脱氧-甘露糖基糖基)甲酰胺2和10,它们与AgOCN,AgSCN或KSCN在硝基甲烷中反应导致形成glycopyranosylidene-spirohydantoins 3,11和15和-thiohydantoins 7和16。普伦脱乙酰化,得到吡喃外延-hydantocidin类似物4和12,以及thiohydantocidin类似物8和17, 分别。
