Abstract
In our previous papers we described the preparation of 3-β-D-glucopyranosyloxy) and 3-β-D-galactopyranosyloxy) derivatives of steroids with an α,β-unsaturated ester chain in position 17β of androstane skeleton. In conection with this project we have studied silver silicate promoted glycosylation of some of above mentioned steroidal derivatives with 2,3,4-tri-O-acetyl-6-deoxy-α-D-glucopyranosyl bromide and 2,3,4-tri-O-acetyl-6-deoxy-α-L-mannopyranosyl bromide.
