Aryl gem-disubstituted conjugated alkenols underwent oxidative cyclization affording 2,5,5-trisubstituted tetrahydrofurans in reasonable yields and good diastereoselectivities using the reductive termination variation of the Mukaiyama aerobic oxidative reaction. Under oxidative termination, the same alkenols produced diols and ketonic by-products via the double hydration and beta-scission competing pathways. Furthermore, the differences in alkenol reactivity under the reductive and oxidative termination conditions were investigated.

Asymmetric cyclization of 4-aryl-4-pentenals by using a cationic [Rh((R)-BINAP)]ClO4 afforded (3R)-3-substituted cyclopentanones; on the other hand, the cyclization of 4-pentenals bearing ortho-halogeno phenyl groups afforded the opposite (3S)-ones.
