2,5-Disubstituted 1,3-dioxacycloalkanes have recently been found to be promising lead compounds that possess potent anti-inflammatory activity and therefore may act as chemo-prevention agents. Encouraged by this we have designed and synthesized a new series of 5-amino-2-heteroaryl-1,3-di-oxanes. Starting from N-protected 2-aminopropane-1,3-diol and the corresponding aromatic aldehydes, the products
最近发现 2,5-二取代的 1,3-二氧杂环烷烃是有前途的先导化合物,具有有效的抗炎活性,因此可以作为化学预防剂。受此鼓舞,我们设计并合成了一系列新的 5-amino-2-heteroaryl-1,3-di-oxanes。从 N-保护的 2-氨基丙烷-1,3-二醇和相应的芳香醛开始,在脱保护步骤中分离产物而没有异构体反转。这是第一个广泛适用的合成方法,用于将杂芳醛缩醛化以得到 5-氨基-1,3-二氧六环。我们的路线提供了对这种二恶烷的两种异构体(即顺式和反式产物)以及 4-(羟甲基)-2-杂芳基恶唑烷的温和访问,它们是有机合成中有用的构建单元。
