Whereas the ketones 1 were obtained in high yield by reacting the allylic a
lcools 2 with the IBX reagent, treatment of the phenylthio-substituted alco
hol 2d with BaMnO4 afforded, besides the expected ketone 1d, the keto-aldeh
yde 3, presumably formed from 1d by a free-radical chain process. (C) 1999
