摘要

Abstract A synthetic pathway to 3-methylisoxazolo [4, 5-d] pyridazine and some of its derivatives is described. Uv irratiation of 4, 7-dimethoxy (XVII) and 7-chloro-4-hydrazino-3- methylisoxazolo [4, 5-d] pyridazine (IX) shows that both intramolecular rearrangements and solvent involving reactions can occur.
