prepared in an enantiomerically pure form by reduction of dl-ketone with respective (+)- and (−)-Darvon-LiAlH4 complex followed by purification with the aids of esterification with d- and l-menthoxyacetyl chlorides and (−)-camphanic acid chloride, respectively. Absolute configuration of naturally occurring (+)-mayol and (+)-cembrenene was determined by correlation with enantiomerically pure compounds
通过用相应的 (+)- 和 (-)-Darvon-LiAlH4 复合物还原 dl-酮,然后借助 d- 和 l- 的酯化进行纯化,以对映体纯形式制备顺式和反式 1-羟基-neocembrenes分别为薄荷氧基乙酰氯和 (-)-莰酰氯。天然存在的 (+)-mayol 和 (+)-cembrenene 的绝对构型通过与对映体纯化合物的相关性确定。
