补充资料：内酰胺
| 内酰胺 lactam 氨基酸分子内的氨基和羧基间失去一分子水而生成的环状化合物。γ或δ-氨基酸易失水形成γ或δ-内酰胺，例如γ-氨基丁酸易失水形成γ-丁内酰胺。γ-丁内酰胺又称四氢毗咯酮，它既具有微弱的碱性，能与盐酸形成盐酸盐；又具有微弱的酸性，能与氢氧化钠形成钠盐。γ-丁内酰胺进行烃化，可生成N-烃基四氢吡咯酮；与乙炔反应，生成N-乙烯基四氢吡咯酮，进一步聚合，生成聚乙烯基四氢吡咯酮。 工业上制造γ-丁内酰胺是用γ-丁内酯与氨在高温高压下反应制得；也可由丁二酰亚胺部分还原制得。δ-戊内酰胺又称六氢吡啶酮，可由δ-戊内酯与氨反应制得。小环内酰胺和大环内酰胺必须由间接方法制备，例如利用乙烯酮与亚胺加成可生成β-内酰胺；利用环酮肟的重排反应合成ε及更高级的内酰胺。 聚乙烯基四氢吡咯酮是血浆的代用品，是接受输血前的一种必要药物，也可作抗生素、局部麻醉药和激素等药物的延效赋形剂。在青霉素、头孢素等的结构中都含有β-内酰胺环。ε-己内酰胺是制造尼龙6纤维的原料。  |
