with specific structural and stereochemical complexity, allowing access to new potential therapeutic entities. In this work, a new strategy based on the [4 + 2] Povarov reaction involving 1,3-diazadiene was developed. This approach is applied for a straightforward procedure in the preparation of chromeno[4,3-d]pyrido[1,2-a]pyrimidine derivatives, with accessible substrates, 2-aminopyridine and unsaturated
药物发现的基石是制定策略,提供具有特定结构和立体化学复杂性的特殊小分子,从而获得新的潜在治疗实体。在这项工作中,开发了一种基于涉及 1,3-二氮杂二烯的 [4 + 2] Povarov 反应的新策略。该方法适用于制备色并[4,3- d ]吡啶并[1,2- a ]嘧啶衍生物的简单过程,具有可接近的底物、2-氨基吡啶和不饱和醛,以及优异的原子经济性以获得四个稠合环杂环,以区域和非对映选择性方式。
