摘要：

Pyrrolo[1,2-b]pyridazine derivatives were synthesized for the first time by 1,3-dipolar cycloaddition reaction between mesoionic 1,3-oxazolo[3,2-b]pyridazinium-2-oxides and acetylenic dipolarophiles. The isolation and characterization of the stable mesoionic oxazolo[3,2-b]pyridazines are also presented.
