A process for producing amide derivatives represented by general formula (XV) or enantiomers thereof, novel intermediate compounds useful for producing these compounds, etc., and a process for producing the same, wherein each symbol is as defined in the specification. Compared with the conventional processes, the above process can be very easily effected and enables an efficient production of the compounds (XV), i.e., those involving the compounds (XVI) having an HIV protease inhibitory effect in high yields. The novel intermediates are highly advantageous as intermediates for producing not only the above compounds (XVI) but also those which are useful as an X-ray contrast medium, etc.
一种生产通式(XV)代表的酰胺衍生物或其对映体、用于生产这些化合物的新型中间体化合物等的工艺,以及生产这些化合物的工艺,其中各符号如说明书中所定义。与传统工艺相比,上述工艺非常容易实现,并且能够高效生产化合物 (XV),即涉及具有 HIV 蛋白酶抑制作用的化合物 (XVI) 的高产率生产。这种新型中间体作为生产上述化合物(XVI)以及用作 X 射线造影剂等的中间体具有极大的优势。
