Riedl, Zsuzsanna published the artcileSynthesis of novel 1-methyl-1H-pyridazino[3,4-b]indoles, Quality Control of 146140-95-6, the publication is Tetrahedron (2006), 62(1), 121-129, database is CAplus.
New synthetic pathways have been elaborated to 1-methyl-1H-pyridazino[3,4-b]indoles starting from halopyridazin-3(2H)-ones. Suzuki cross-coupling reaction of chloro, iodo, dichloro, and dibromo substituted pyridazin-3(2H)-ones with 2-pivaloylaminophenylboronic acid followed by hydrolysis of the amide and subsequent ring closure via condensation gave fused indoles. Some of these compounds showed biol. activity as antitrypanosomal agents.
