The Curtius rearrangement of cyclohex-3-ene carboxylic acid using diphenylphosphoryl azide in the presence of triethylamime and ethanol, t-butanol or benzyl alcohol has been described. As a result the synthesis of ethyl, t-butyl or benzyl N-(1-cyclohex-3-enyl)carbamates has been achieved in one pot, in good chemical yield. A series of transformations of benzyl N-(1-cyclohex-3-enyl)carbamate, such as
已经描述了在三乙胺和乙醇,叔丁醇或苯甲醇的存在下使用二苯基磷酰基叠氮化物对环己-3-烯羧酸的库尔修斯重排。结果,已经在一个罐中以良好的化学产率合成了乙基,叔丁基或苄基的N-(1-环己基-3-烯基)氨基甲酸酯。已经进行了苄基N-(1-环己-3-烯基)氨基甲酸酯的一系列转化,例如碘化和环氧化,以及相应的环氧化物的开环,从而导致一些有用的氧化环己基lamimo构件。
