6-(Pyridyl)salicylates were regioselectively prepared by formal [3+3] cyclization of 1,3-bis(silyl enol ethers) with 3-(pyridyl)-3-silyloxy-2-en-1-ones. These reactions represent what are, to the best of our knowledge, the first [3+3] cyclizations of 1,3-bis(silyl enol ethers) with heterocyclic substrates.
6-(吡啶基)水杨酸盐是通过1,3-双(甲硅烷基烯醇醚)与3-(吡啶基)-3-甲硅烷氧基-2-烯-1-酮的形式[3+3]环化反应制备的。据我们所知,这些反应代表了 1,3-双(甲硅烷基烯醇醚)与杂环底物的第一个 [3+3] 环化反应。
