2,3,4,6‐Tetra‐O‐acetyl‐α‐D‐glucopyranosyl bromide (1) reacts with 5‐benzyl‐3‐phenyl‐1,2,4‐triazin‐6(1H)thiones 6a‐d and 4‐aryl‐6‐benzyl‐3‐thioxo‐2,3,4,5‐tetrahydro‐1,2,4‐triazin‐5‐ones 11a‐g to give the corresponding N‐glucosyl derivatives 7a‐d and 12a‐g, respectively. The structures of these glucosides were established by chemical and spectroscopic methods.
