A golden dig! Gold‐catalyzed direct access to functionalized 2H‐1‐benzoxocines, eight‐membered‐ring ethers, is described. This unprecedented synthesis of benzoxocines occurs by an 8‐endo‐dig cyclization of the 1,7‐enyne substrates.
挖金!描述了金催化直接接触官能化的2 H -1-苯并氧杂庚酮,八元环醚。苯并恶臭酮的这种空前的合成是通过对1,7-烯炔底物进行8内消旋环化而实现的。
