AROMATIC SUBSTITUTED GLYCOSIDE

摘要

An aromatic substituted glycoside is disclosed of the formula <IMG> wherein the configuration of the substituted -OR on the anomeric carbon is alpha, n is an integer of 0 or 1, and R is a substituted aromatic radical selected from the group (a) <IMG> (b) <IMG> and (c) <IMG> where R1 through R6 are independently halogen, NO2, SO3H, <IMG>, <IMG>, <IMG>, <IMG> , where R7 is lower alkyl; and includes its stereoisomers, optical isomers and geometric isomers and mixtures of the foregoing isomers. These substrates are useful as direct substrates for alpha-amylases. A process for the preparation of the substrates and related substances is also described.
