摘要: Abstract The reaction of (−)-camphorquinone with excess moist bromine gives (−)-(1S,5S)-1-bromomethyl-3,3-dibromo-8,8-dimethyl-7-oxabicyclo[3.2.1]octane-2,6-dione rather than 1-bromomethyl-3,5-dibromo-8,8-dimethyl-7-oxabicyclo[3.2.1]octane-2,6-dione as has been reported in the literature. controlled leads to (−)-(1S,5S)-3,3-dibromo-1,8,8-trimethyl-7-oxabicyclo[3.2.1]octane-2,6-dione and not 5-bromo-1-bromomethyl-8,8-dimethyl-7-oxabicyclo[3.2.1]octane-2,6-dione.
