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.
通过介离子型 1,3-噁唑并[3,2-b]哒嗪鎓-2-氧化物与乙炔基双极性化合物之间的 1,3-二极环加成反应,首次合成了吡咯并[1,2-b]哒嗪衍生物。此外,还介绍了稳定的介离子恶唑并[3,2-b]哒嗪的分离和表征。
