The ruthenium tetroxide oxidation of cyclic N-acyl amines by a 10% NaIO4 aqueous solution containing tert-butanol as a single layer system resulted in the endo-cyclic C–N bond cleavage to afford the ω-amino acids as almost sole products in good yields, while a similar oxidation under the double layer using a NaIO4 aqueous solution, and ethyl acetate gave the N-acyl lactams.
含叔丁醇作为单层系统的10%NaIO 4水溶液对环N-酰基胺的四氧化钌氧化导致环内C-N键断裂,从而提供ω-氨基酸,几乎是唯一的产物。良好的收率,同时使用NaIO 4水溶液和乙酸乙酯在双层下进行类似的氧化,得到N-酰基内酰胺。
