isocyanurates 2a-c were synthesized from alpha, omega-dibromoalkanes 5 in four steps. The alkylation of the bromides 5a-c with O-benzyl-N-[(trichloroethoxy)carbonyl]hydroxylamine in the presence of DBU gave N-alkylation products 7a-c. The (trichloroethoxy)cabronyl protecting group of 7a-c was easily removed by Zn dust in acetic acid. When the reaction was performed with acetic anhydride, the desired N-acetylated
