In this paper, a novel general route to the stereospecific synthesis of chiral dihydropyridazines relying on the stereospecific formation of 1,4-diones is presented. The chirality is provided through the application of bicyclic lactams to the synthesis of the required diones. Treatment of the diones with hydrazine produces the pyridazine targets. In this report, the synthesis of four chiral 6-phenyl-4
在本文中,提出了一种新的一般路线,该路线依赖于1,4-二酮的立体定向形成,用于手性二氢哒嗪的立体定向合成。通过将双环内酰胺应用于所需的二酮的合成来提供手性。用肼处理二酮产生哒嗪靶。在该报告中,还介绍了四种手性6-苯基-4,4-二取代-1,4-二氢哒嗪的合成方法。
