A new synthetic method for 1,4-benzodiazepine-2,5-dione (BZD) was accomplished by the coupling of amino acid N-carboxy anhydrides (NCAs) with Boc-anthranilic acid, followed by the deprotection of Boc group and by the ring expansion.
通过将
氨基酸N-
羧酸酐(NCA)与Boc-
邻氨基苯甲酸偶合,然后将Boc基团脱保护并通过Boc脱保护,从而完成了1,4-苯并二氮杂-2,5-二酮(
BZD)的新合成方法。环膨胀。
