Abstract

4(R)‐(6‐Chloro‐s‐triazolo[4,3‐b]pyridazinyl‐3)‐1,4‐furanoses 10 and 11, 5(R)‐(6‐chloro‐s‐triazolo[4,3‐b]pyridazinyl‐3)‐1,5‐pyranose 13, and 2(S),3(R)‐dihydro‐5‐(6‐chloro‐s‐triazolo[4,3‐b]pyridazinyl‐3)‐2,3‐O‐isopropylidenefuran (12) were prepared by cyclization of hydrazones 6–9 obtained from 6‐chloro‐3‐hydrazinopyridazine (1) and aldofuranoses 2, 3 and 4, and aldopyranose 5.
