A new preparative method for N-adamantylation of carboxylic acid amides, ureas and for C5-adamantylation of barbituric acid in trifluoroacetic acid (TFA) is proposed. Tertiary 1-adamantanols and 1-(1-adamantyl)alkanols were used as adamantylating agents. The reaction of 1-(1-adamantyl)alkanols with nitriles in TFA solution was employed for the first time for the preparation of N-[1-(1-adamantyl)alkyl]amides.

脲的N-
金刚烷基化和
巴比妥酸的C5-
金刚烷基化的新制备方法。使用了三级的
1-金刚烷醇和1-(1-
金刚烷基)烷醇作为
金刚烷基化试剂。首次采用了1-(1-
金刚烷基)烷醇与腈在TFA溶液中的反应来制备N-[1-(1-
金刚烷基)烷基]酰胺。
