Abstract

Synthesis of steroid glycoside sulfates sulfated both on the steroid skeleton and in sugar part are presented. Sodium salts of 5α-cholestane-3β,6α-diol 6-β-D-glucoside 3-sulfate V and 3-β-D-glucoside 6-sulfate XI were prepared from 3β-(2-tetrahydropyranyloxy)-5α-cholestan-6α-ol (I) using acetyl and methoxymethyl groups for temporary protection. Sulfation in the sugar part was at first checked in pregnane series and triethylammonium salts of 3β-(β-D-glucopyranosyloxy)pregn-5-en-20-one 6'-sulfate (XXVI) and 4'-sulfate 2',3'-diacetate XXVII were prepared. Application of the method on cholestane derivatives gave triethylammonium salt of 5α-cholestan-3β-yl β-D-glucopyranoside-6-sulfate (XXXI).
