PROCESS FOR PREPARING NITROAROMATIC GLYCOSIDES

摘要

E.I. du Pont de Nemours and Company 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 nitroaromated glycosides are useful as standard substrates for the assay of .alpha.-amylase.
