Pyridine rings are common structural motifs found in a number of biologically active compounds, including some top-selling pharmaceuticals. We have developed a new approach to access substituted pyridines. The method aims to provide a reliable synthesis of a diverse range of substituted pyridines through a three-step procedure. Readily available enones are first converted into 1,5-dicarbonyls through
吡啶环是在许多生物活性化合物(包括一些畅销药物)中发现的常见结构基序。我们已经开发出一种新的方法来获得取代的吡啶。该方法旨在通过三步法提供可靠的合成范围广泛的取代吡啶。易于获得的烯酮首先通过两步Hosomi-Sakurai烯丙基化/氧化裂解序列转化为1,5-二羰基,然后使用盐酸羟胺将其环化为相应的吡啶。使用该方法已经合成了多种取代的吡啶。
