Process for preparing nitroaromatic glycosides

摘要

A process for preparing nitroaromatic glycosides is described. The process comprises contacting an acetylated glycoside of maltotetraose, maltopentaose or maltohexaose with a phenol, nitrating the resulting product to place a NO2 group on the aromatic moiety and deacetylating the nitrated product. The nitroaromatic glycosides are useful as standard substrates for the assay of alpha -amylase.
