内型异莰烷基乙酮的合成新法

本文报道了一种新型香料化合物内型异莰烷基乙酮的又一新的合成方法，即先使莰烯进行直接ω-乙酰化反应制得ω-乙酰基莰烯，再使后者在钯催化下进行氢化。该法大大简化了合成路线和工艺，操作简便易行，有利于走向工业化。

The paper reports a new way for synthesis of endo-isocamphanyl methyl ketone-a new per-fume, the compound was synthesized by Pd catalytic hydrogenation of the direct ω-acetylca-mphene which was prepared from camphene by the direct-acetylation. Compared with reportedmethod, this one had fewer steps, more convenient operation and be advantageous to realize in- dustrialization.
