Selective C–H acylation of quinolin-2(1H)-one with α-oxocarboxylic acids at the C3 position by sliver catalysis and its application in the synthesis of palbociclib
An efficient and selective method C3-H acylation of quinolin-2(1H)-one with at the C3 position has been developed. Active molecules containing acylquinolones were synthesized by silver-catalyzed decarboxylation of α-oxycarboxylic acids with quinolin-2(1H)-one in moderate to good yields. This reaction affords a broad substrate scope and good tolerance of functional groups. In addition, using this protocol
开发了一种在 C3 位对 quinolin-2(1 H )-one 进行有效且选择性的 C3-H 酰化方法。通过银催化 α-羟基羧酸与喹啉-2(1 H )-酮的脱羧反应合成了含有酰基喹诺酮的活性分子,产率中等至良好。该反应提供了广泛的底物范围和良好的官能团耐受性。此外,利用该方案,可以轻松合成市售药物Palbociclib。
