Novel pyrazolopyridine-4-yl pyridazinone derivatives serve as phosphodiesterase inhibitors and are useful compounds for use in pharmaceutical products.
Specifically, the compounds of the present invention are pyrazolopyridine-4-yl pyridazinone derivatives represented by the following general formula (1):
(Example: 6-(2-ethyl-7-methoxy-pyrazolo[1,5-a]pyridine-4-yl)-5-methyl-4, 5-dihydro-3(2H)-pyridazinone).

ubiquitous in pharmaceuticals and drug-like compounds; however, regioselective synthesis has proved challenging. Herein we report our efforts to develop a regioselective method for the synthesis of pyrazolo[1,5-a]pyridines and the serendipitous discovery of a protocol for the regioselective formation of imidazo[1,5-a]pyridines. Together, these transformations allow for the rapid and selective formation
含氮杂环在药物和类药物化合物中无处不在;然而,区域选择性合成已被证明具有挑战性。在此,我们报告了我们为开发合成吡唑并[1,5- a ]吡啶的区域选择性方法所做的努力,并偶然发现了一种用于区域选择性形成咪唑并[1,5- a ]吡啶的方案。总之,这些转化允许从一个共同的中间体快速和选择性地形成两个重要的杂环基序。
