已经证明了一种有效的单锅三组分多米诺骨牌策略,该策略用于在空气中高产率地使用催化量的氯化Fe(III)合成咪唑并[1,2- a ]吡啶。通过使易得的醛与2-氨基吡啶在硝基烷和DMF(2:1)的混合物中反应,合成了咪唑并[1,2- a ]吡啶文库。该转化大概是通过顺序的氮杂-亨利反应/环化/脱硝而发生的。使用容易获得的化学品作为起始原料,廉价的金属催化剂,好氧反应条件,宽泛的官能团耐受性和操作简便性是本方案的显着优势。

The invention provides compounds of Formula I or Formula II:
or a pharmaceutically acceptable salt or ester, thereof, as described herein. The compounds and compositions thereof are useful for treating Pneumovirinae virus infections. The compounds, compositions, and methods provided are particularly useful for the treatment of Human respiratory syncytial virus infections.
An efficient, one-pot, three-component domino strategy has been demonstrated for the synthesis of imidazo[1,2-a]pyridines using a catalytic amount of Fe(III) chloride in high yields in air. A library of imidazo[1,2-a]pyridines was synthesized by the reaction of easily available aldehydes and 2-aminopyridines in a mixture of nitroalkane and DMF (2:1). This transformation presumably occurs by a sequential
