The previous assignment of a cis conformation to cyclohexyl 2-carbamylcyclohexylamine, which was prepared by the condensation of urea with cyclohexanone, has been confirmed by equilibration in the presence of potassium t-butoxide. The failure of 4-t-butylcyclohexyl 2- carbamyl-4-t-butylcyclohexylamine to equilibrate under the same conditions is discussed in relation to its structure. 1, 2, 3, 4, 5, 6, 7, 8-Octahydroacridine was prepared by the ...
