The synthesis of 1 -acetyl-bicyclo[2.2.2]octane oxime is described. The p-toluene-sulfonic ester of this compound affords l-acetamido-bicyclo[2.2.2]octane (7) upon BECKMANN rearrangement, and therefore possesses the anti-R/OTs configuration 6.1 -Acetamido-bicyclo[2.2.2]octane (7) is also obtained by the HOFMANN reaction of l-carbamoyl-bicyclo[2.2.2]octane (3).
描述了1-乙酰基-双环[2.2.2]辛烷肟的合成。该化合物的对甲苯磺酸酯在BECKMANN重排后提供1-乙酰氨基-双环[2.2.2]辛烷(7),因此具有抗-R / OTs构型6 .1-乙酰氨基-双环[2.2.2]也通过1-氨基甲酰基-双环[2.2.2]辛烷(3)的HOFMANN反应获得]辛烷(7)。
