Many important drugs contain a class of preferred motifs called bisindoles. The development of synthetic approaches for bis(indolyl)methanes (BIMs) offers numerous advantages. However, most methods for synthesizing BIM derivatives require metal catalysts.
This study aimed to synthesize bisindoles via oxidative cleavage of 1,2-diols using periodic. acid.
For the synthesis of bisindoles via oxidative cleavage of 1,2-diols, periodic acid was used. It is a gentle, reasonably priced, and effective testing agent for the synthesis of bisindole analogs from a range of 1,2-diols. Aldehydes were produced by the in situ oxidation of 1,2-diols by periodic acid, and they reacted with indoles to generate a range of bisindoles. The HIO3 generated in situ from periodic acid accelerated the reaction. The structures of the compounds were confirmed by NMR (1H and 13C), high-resolution mass spectrometry (HRMS), and elemental analysis using a CHNSO analyzer.
A variety of BIMs derivatives were produced by oxidatively breaking down 1,2-diols using periodic acid. The appealing aspects of this procedure include its high yield, rapid response time, and catalyst-free conditions.
In this study, a productive and sustainable method for creating BIMs derivatives is presented. The procedure is genuinely green since it uses periodic acid as an oxidizing agent rather than a conventional catalyst, has a clean reaction profile, quick reaction times, and is inexpensive.
