N-benzyl carboxamides and in particular the corresponding tert-butyl acylcarbamates are reported. These compounds were required to study the postulated effect of various heterocycles (pyridine and pyrazine with and without condensed benzene rings) on the cleavage of acyl–N bonds by reduction. All compounds were initially characterized by cyclic voltammetry (CV) which indicated various degrees of facilitated
报道了与一组杂芳族N-苄基羧酰胺,尤其是相应的叔丁基酰基氨基甲酸酯有关的合成和光谱学细节。这些化合物是研究各种杂环的假定作用所必需的(吡啶 和 吡嗪带有和不带有稠合苯环)对酰基-N键的裂解减少。所有化合物的最初特征是循环伏安法 (简历)表示各种程度的促进还原,反映了杂环成分的直接影响。研究了选择的酰基氨基甲酸酯在轻度条件下对酰基-N键的裂解作用还原剂,并通过活性铝和 硼氢化钠。转化为酰基氨基甲酸酯,然后减少 因此可能是一个温和,有效的两步程序,可实现卵裂 酰胺类,允许隔离氨基甲酸酯和 硼氢化钠 也是对应的 酒类。
