Rearrangement of oxiranes, on contact with active Al2O3, earlier studied with methyldialkyl-substituted 1,2-epoxides, has now been extended to 1,2-dialkyl epoxides (cyclohexene oxide, cycloheptene oxide) and β-himachalene monoepoxide (tetrasubstituted). Isomerisation of citronellol epoxide has been investigated to detect any participation of the OH function in oxirane opening. To gauge the importance
先前与甲基二烷基取代的1,2-环氧化物研究过的环氧乙烷与活性Al 2 O 3接触后的重排现已扩展至1,2-二烷基环氧化物(环己烯氧化物,环庚烯氧化物)和β-him麻单环氧化物(四取代) )。已经对香茅醇环氧化物的异构化进行了研究,以检测OH官能团在环氧乙烷开口中的任何参与。为了衡量3β,4β-环氧丙烷重排底物拓扑结构的重要性,已将结果与较早使用3α,4α-环氧丙烷进行重排的结果进行了比较。
