, p. 1931 - 1934 (2008/09/19)
Two synthetic routes to the versatile 3,5-dihydro-imidazo[4,5-d]pyridazin-4-ones 2 and 5 have been developed that allow the production of multigram quantities without the need of any chromatographic purification. Broad and selective elaboration of the heteroaromatic scaffolds has also been accomplished.
