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 condensation of 2,2′-methylene-bis-cyclohexanone with urea.
通过在叔丁醇钾存在下的平衡,证实了先前将顺式构象分配给环己基 2-氨基甲酰基环己胺,它是通过尿素与环己酮的缩合制备的。4-t-丁基环己基2-氨基甲酰基-4-t-丁基环己胺在相同条件下无法平衡的问题就其结构进行了讨论。1,2,3,4,5,6,7,8-八氢吖啶是由 2,2'-亚甲基-双-环己酮与尿素缩合制备的。
