The first synthetic access to stable and acyclic 1,3‐butadienes with two electron‐withdrawing carbonyl groups and their potential to deliver new molecular scaffolds through intriguing endo‐selective Diels–Alder cycloadditions are presented. The bicyclic scaffolds produced through the cycloaddition chemistry of electron‐deficient dienes afforded potent Hedgehog signaling pathway inhibitors.
介绍了首次合成获得具有两个吸电子羰基的稳定且无环的1,3-丁二烯,以及它们通过吸引人的内选择性Diels-Alder环加成反应提供新分子支架的潜力。通过缺电子二烯的环加成化学产生的双环支架提供了有效的Hedgehog信号通路抑制剂。
