Process for producing hexahydrofurofuranol derivative |
abstract |
The present invention provides; a process for producing a compound (IV) comprising a step of reacting a compound (I) with a compound (II) in the presence of an optionally substituted cyclic secondary amine to obtain a compound (III) and a step of sequentially or simultaneously eliminating R 1 and R 2 from the compound (III), and then cyclizing the R 1 - and R 2 -eliminated compound to obtain the compound represented by the formula (IV); a process for producing a high purity compound (IV); an intermediate thereof; and a process for producing an intermediate. |
