(−)-carvone with LiAlH4, NaBH4, and (i-Bu)2AlH was performed. It was found that the reduction with the system CeCl3 · 7 H2O-NaBH4 in methanol at 20°C is the most practical procedure for the synthesis of (−)-carveol. Solvolysis of (−)-carvyl methanesulfonate gave products of SN2 and SN2′ replacement of the methylsulfonyloxy group, the latter slightly prevailing. Overman rearrangement of (−)-carveol resulted
用LiAlH 4,NaBH 4和(i- Bu)2 AlH还原(-)香芹酮中的氧代基。发现在20℃下在甲醇中用CeCl 3 ·7 H 2 O-NaBH 4体系还原是最有效的合成(-)-香芹酚的方法。(-)-甲磺酸甲磺酸盐的溶剂分解得到S N 2和S N的产物2'取代了甲基磺酰氧基,后者略占优势。(-)-香芹酚的超量重排导致形成相应的三氯乙酰胺衍生物,并且标题化合物的分子内碘代醚化提供了6-碘甲基-2,6-二甲基-7-氧杂双环[3.2.1] oct-2-ene。
