摘要

以偕胺肟为原料，采用一锅法合成1,2,4-恶二唑，制备了药物阿塔卢酮。这种一锅法是通过DMAP催化偕胺肟的o -酰化，然后在DMSO中氢氧化钾存在下进行环化，原位形成o -酰基胺肟。用该方法合成了17个1,2,4-恶二唑，分离收率高达94%，完成了阿塔卢酮的合成。

Synthetic preparation of Ataluren via a one-pot synthesis of 1,2,4-oxadiazoles employing a DMAP catalyzed amidoxime O-acylation/cyclization pathway

The drug ataluren has been prepared using a one-pot synthesis of 1,2,4-oxadiazoles from amidoximes. This one-pot approach involves the in situ formation of O-acylamidoximes via the DMAP catalyzed O-acylation of amidoximes followed by cyclization in the presence of potassium hydroxide in DMSO. Using this methodology, a series of 17 examples of 1,2,4-oxadiazoles were formed in isolated yields up to 94% and the synthesis of ataluren was completed.
