A new base-induced rearrangement of furoxans, viz., a recyclization of 4-amidino-3-Rfuroxans into 1-substituted 3-(1-nitroalkyl)-5-R-1H-1,2,4-triazoles in the presence of alkali metal alkoxides and into 3-acyl-5-R-1H-1,2,4-triazoles in aqueous alkaline solutions, was found.
一种新的碱诱导呋喃烷重排,即在存在下将 4-脒基-3-Rfuroxans 再环化为 1-取代的 3-(1-硝基烷基)-5-R-1H-1,2,4-三唑发现了碱金属醇盐并在碱性水溶液中转化为 3-酰基-5-R-1H-1,2,4-三唑。
