  名称：

  Synthesis of 2-bromo-7-methyl-3,5-dihydro-imidazo[4,5-d]pyridazin-4-one and 3-alkyl-2-bromo-3,5-dihydro-imidazo[4,5-d]pyridazin-4-one and their selective elaboration

  摘要：

  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. (c) 2008 Elsevier Ltd. All rights reserved.
