Four spirocyclopropylamines in which the adjacent spiro ring was varied from cyclopropyl to cyclohexyl have been synthesized and deaminated. Three of the amines, 1- aminospirohexane, 1-aminospiro [2.4] heptane, and 1-aminospiro [2.5] octane, were obtained by adding ethyl diazoacetate to the appropriate methylenecycloalkane, and converting the resulting spiro esters by hydrolysis and Curtius rearrangement into the ...
