概要

• 論文の詳細を見る

• Treatment of (3,3-dialkyl-2,2-dichlorocyclopropyl)methanols with hydrobromic acid gives 2-cyclopentenones through postulated intermediates, 3-chlorocyclopentadienyl cations. Another method which should give the same cationic intermediates involves trifluoroacetic acid catalyzed reaction of 3,3-dichloro-1-alken-4-ols. This is found to be particularly useful for cyclopentenone annulation.
