摘要
报导以邻甲苯胺为原料经氧化－还原反应合成鹿蹄草素方法的改进。采用Ｆｅ／ＨＣＩ还原方法后，使还原反应收率达到了９６．１％，二步总收率提商到了４８．１％。该工艺具有反应时间短、工艺简单、收率高的优点。经熔点、元素分析、红外、紫外光谱证明了该产品的结构。
The paper reported an improved method in synthesis of pyrolin from o-toluidineby Fe/HCI reductive step. The yield was up to 96.1%, and the. total yieldv 48.1%. This newmethod has theadvantage of short-time and high-yield. The structure of pyrolin was proved byMP, element analysis, UV and IR.
