Process for selective production of aryl 5-thio-beta-d- aldohexopyranosides

摘要

The present invention provides a method for preparing an aryl 5-thio-beta-D-aldohexopyranoside derivative of Formula (III), which comprises reacting a 5-thio-D-aldohexopyranose derivative of Formula (I) with Ar-OH of Formula (II) in the presence of a phosphine represented by PR¹¹R¹²R¹³ and an azo reagent represented by R²¹-N-N-R²² in accordance with the following scheme.
