Silylated benzamides 2, available by directed ortho metalation, undergo fluoride-induce carbodesilylation and ipso bromodesilylation to give usefully-substituted aromatics 3 and 4; these reactions are utilized in a short and efficient synthesis of erythrolaccin tetramethyl ether 10.
可以通过直接原金属化得到的甲硅烷基化的苯甲酰胺2进行氟化物诱导的碳硅烷基化和ipso溴代甲硅烷基化,得到有用取代的芳族化合物3和4;这些反应可用于快速有效地合成红霉素四甲醚10。
