摘　　要：本文研究了龙脑脱氢制光学活性樟脑,所用龙脑为天然产物或由α-蒎烯水合制得。脱氢反应在气相中进行,一种含锌固体作催化剂,收得率在95％以上。产物樟脑纯度高,并具有与原料几乎相同的光学纯度。Optically active camphor(3)was synthesized via dehydrogenation of n-borneol(2a) which was natural product or obtained via hydration of 2- pinene(1) by one step. The dehydrogenation was carried out in the presence of Zn-laden catalyst, in gas-phase, without any solvents, and with good yield. The camphor obtained possesses almost the same optical pureness as its starting material-natural n-borneol or 2-pinene.
