Abstract

Williamson etherification of (1) with propargyl bromide afforded the 1-O-propargyl-2,3:5,6-Di-O-isopropyli-dene α-D-mannofuranoside (2) in a very good yield . 1,3-Dipolar cycloaddition of (2) with four different aryl azides derivatives using click conditions gave four novel 1,2,3-triazole derivatives containing sugar moiety . The biological activity of synthesized compounds were tested against urease activity by immobilize this enzyme on the synthesized compounds . All of these compounds show inhibition activity of enzyme. Some of these compounds (T1) show high inhibition action on the enzyme activity , while (T2,T3,T4) show moderate effect on the activity .
