一种实用高效的6-羰基烷氧基-13-环烷基-5 H-吲哚并[2,1- a ] [2]苯并ze庚因-10-羧酸衍生物的合成
摘要:
已经开发了方便且实用的6-羰基烷氧基-13-环烷基-5 H-吲哚并[2,1- a ] [2]苯并ze庚因-10-羧酸衍生物(6)的合成方法。合成的关键步骤是利用迈克尔加成反应的分子内串联反应顺序,然后是半缩醛11与2-(二甲氧基磷酰基)丙烯酸甲酯12之间的Horner-Wadsworth-Emmons(HWE)烯化反应。环的构建有效地发生,并且产物6的纯化是直接的。6a的C-10甲酯选择性水解为羧酸13,而6d的烯烃在NaH存在下,使用三甲基碘化碘在DMSO中将其转化为环丙烷14。
The invention encompasses compounds of formula I as well as compositions and methods of using the compounds. The compounds have activity against hepatitis C virus (HCV) and are useful in treating those infected with HCV.
