1-Acylamino-1-(trimethylsiloxy)alkanes react with carbon and heteroatom nucleophiles to give the corresponding 1-substituted-1-acylaminoalkanes. The 1-acylamino-1-(trimethylsiloxy)alkanes can also give rise to enamides, and by this route the mild antibiotic tuberin, and the isomeric (Z)-tuberin have been prepared. A further example of their reactions is illustrated with the acid-catalysed intramolecular cyclisation onto a carbon–carbon double bond. These transformations show that 1-acylamino-1-(trimethylsiloxy)alkanes are versatile precursors to synthetically useful acylimines.
1-酰氨基-1-(三甲基硅氧基)烷烃与碳和杂原子亲核试剂反应,生成相应的1-取代-1-酰氨基烷烃。1-酰氨基-1-(三甲基硅氧基)烷烃还可以生成烯酰胺,通过这种途径,可以制备出温和的抗生素肽霉素及其异构体(Z)-肽霉素。它们反应的另一个例子是酸催化的分子内环化反应,发生在碳-碳双键上。这些转化表明,1-酰氨基-1-(三甲基硅氧基)烷烃是合成有用酰亚胺的多功能前体。
