Structural Revision and Synthesis of Altechromone A was written by Koenigs, P.;Rinker, B.;Maus, L.;Nieger, M.;Rheinheimer, J.;Waldvogel, S. R.. And the article was included in Journal of Natural Products in 2010.Reference of 1634-34-0 This article mentions the following:
The chromone “altechromone A” was synthesized as a substructure in the course of natural product synthesis. Its architecture was verified by X-ray anal., but spectroscopic data showed a strong deviation from the reported data. By comparison with the synthesized isomers the structure of altechromone A was revised to structure I. In the experiment, the researchers used many compounds, for example, 2′,6′-Dihydroxy-4′-methylacetophenone (cas: 1634-34-0Reference of 1634-34-0).
2′,6′-Dihydroxy-4′-methylacetophenone (cas: 1634-34-0) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Reference of 1634-34-0
