2‐Benzylidenecyclopentanol ( 2 ) can be epoxidized stereoselectively to furnish 2‐ trans ‐benzylidene‐1β‐hydroxycyclopentane β‐oxide ( 4 ) with either t ‐butyl hydroperoxide in the presence of vanadium catalyst or m ‐chloroperoxybenzoic acid. Epoxidation of 3‐ trans ‐benzylideneisoborneol ( 10 ) with t ‐butyl hydroperoxidevanadium catalyst furnishes stereoselectively 3‐ trans ‐benzylideneisoborneol exo ‐oxide ( 11 ) whereas epoxidation of alcohol 10 with m ‐chloroperoxybenzoic acid furnishes stereoselectively 3‐ trans ‐benzylideneisoborneol endo ‐oxide ( 14 ).
