first examples of this class of compound, was achieved by Vilsmeier formylation and cyclisation of the acyl enamine 6. The triflate 2 was found to undergo a range of palladium-catalysed coupling reactions giving a synthetic sequence of general use for the preparation of highly substituted 2-pyridones.
通过维斯迈尔甲酰化和酰基烯胺6的环化反应,可以快速方便地合成3-三氟甲磺酰氧基-2-吡啶酮2,这类化合物的第一个例子。发现三氟甲磺酸酯2经历了一系列钯催化的偶联反应,给出了通常用于制备高度取代的2-吡啶酮的合成序列。
