Stereoselective rearrangement of cis-5-(4-methoxybenzyl)-spiro[5,2]-octan-4-ol cis-1 in acidified THF-90% H2O2 affords 9-oxabicyclo[6.2.1]nonyl hydroperoxides 7 and 8 which are converted to medium-ring, keto-butyrolactones 2 and 3.
在酸化的THF-90%H 2 O 2中对顺-5-(4-甲氧基苄基)-螺[5,2]-辛-4-醇顺-1进行立体选择性重排,得到9-氧杂双环[6.2.1]壬基氢过氧化物7和8分别转化为中环酮丁内酯2和3。
