DOI: 10.1002/cbic.201700080
Abstract: A set of mannuronic‐acid‐based iminosugars, consisting of the C‐5‐carboxylic acid, methyl ester and amide analogues of 1deoxymannorjirimicin (DMJ), was synthesised and their pH‐dependent conformational behaviour was studied. Under acidic conditions the methyl ester and the… read more here.
