A new general method for the synthesis of acridine-1,8-diones through CDC coupling of enamino-ketones followed by rearrangement has been developed. This is a Cu(I) catalyzed procedure, based on the cross dehydrogenative coupling of the Csp3–H bond with the Csp2–H bond of enamino-ketones followed by rearrangement to acridine-1,8-diones in the presence of PTSA under an aerobic atmosphere. The synthetic
已开发出一种新的通用方法,该方法通过烯胺酮的CDC偶联然后重排来合成a啶1,8-二酮。这是Cu(I)催化的程序,基于PTSA存在下Csp 3 -H键与烯氨基酮的Csp 2 -H键的交叉脱氢偶联,然后在PTSA存在下重排为a啶-1,8-二酮在有氧气氛下。合成路线已广泛地适用于广泛的烯氨基酮衍生物的从不同的苄基胺,以及具有脂族伯胺衍生Ç α(SP 3)-H键与各种环状的,无环的1,3-二酮类和也使用死的。
