e was reduced with sodium borohydride in the presence of cerium(III) chloride heptahydrate to give the corresponding 7-hydroxy compound, which was rearranged into methyl 7-isopropyl-1,10-dimethyl-1,2,3,4-tetrahydroanthracene-1-carboxylate (14) possessing a rearranged linear abietane skeleton, by a treatment with boron trifluoride etherate. The reduction of 14 with lithium aluminum hydride afforded
在氯化铈 (III) 七水合物存在下,7-oxo-5,8,11,13-abietatetraen-18-oate 甲酯用硼氢化钠还原得到相应的 7-羟基化合物,将其重排为 7-异丙基甲酯-1,10-二甲基-1,2,3,4-四氢蒽-1-羧酸酯 (14),通过用三氟化硼醚合物处理,具有重排的线性松香烷骨架。14 用氢化铝锂还原得到 7-异丙基-1,10-二甲基-1,2,3,4-四氢蒽-1-甲醇 (15)。这进一步转化为7-异丙基-1,1,10-三甲基-1,2,3,4-四氢蒽。15 的甲磺酸酯也重排成 2-异丙基-5,9-二甲基-7,8-二氢-6H-环庚 [b] 萘,具有七元 A 环。
