Article abstract of DOI:10.1021/jo00181a025

The pyrazolopyran 5 is obtained by thermal rearrangement of the diazabicyclooctadienone 3; a concerted <3.3> sigmatropic process is suggested.Treatment of 3 with sodium methoxide in methanol leads to the tetrahydropyridazine 14 and the tetrahydroindazolon
