N′-Dibenzyl-6-hydroxymethyl-6-nitroperhydro-1,4-diazepine was converted into a nitronate via retro-Henry reaction, followed by either Michael reaction with several acrylic derivatives or Mannich reaction with different amines, thus leading to 6-substituted 6-nitroperhydro-1,4-diazepines. The tandem retro-Henry/Mannich reaction was also carried out using benzylamine as base, solvent, and reagent at the same
N,N'-二苄基-6-羟甲基-6-硝基过氢-1,4-二氮杂via通过逆亨利反应转化为亚硝酸盐,然后通过迈克尔反应与几种丙烯酸衍生物或曼尼希反应与不同的胺反应,从而导致6-取代的6-硝基过氢-1,4-二氮杂s。的串联回亨利/曼尼希反应也进行了,使用苄胺作为碱,溶剂和试剂在同一时间。还成功实现了硝基的选择性加氢和完全氢解。
