Achmatowicz reaction
The Achmatowicz reaction, also known as the Achmatowicz rearrangement, is an organic synthesis in which a furan is converted to a dihydropyran. In the original publication by the Polish chemist Osman Achmatowicz Jr. and then ketone reduction with sodium borohydride produce an intermediate from which many monosaccharides can be synthesised.
The Achmatowicz protocol has been used in total synthesis, including those of desoxoprosophylline, pyrenophorin Recently it has been used in diversity [oriented synthesis]
and in enantiomeric scaffolding.
