  5,6,7,8-Tetrahydropyrido[4,3-c]pyridazine: A Lead-Oriented Scaffold with Two Diversity Points

  摘要：

  An approach to the derivatives of 5,6,7,8-tetrahydropyrido[4,3-c]pyridazine, a lead-oriented scaffold with two diversity points, was developed. The method included five steps starting from the readily available 4-piperidone derivatives and allowed for the preparation of the target compounds in 32-35% overall yields. The key step of the sequence included one-pot solvent-free reaction of the corresponding 4-piperidone derivative, glyoxylic acid, and hydrazine.
