The benzeneselenol-catalyzed, tributyltin hydride-mediated addition of phenolic iodides to benzene gives the 3-(hydroxyaryl)-1,4-cyclohexadienes, predominantly. Under conditions of controlled osmoylation, these are converted to the racemic 1,2-syn-2,3-anti-3-(hydroxyaryl)-4-cyclohexene-1,2-diols, whereas exhaustive osmoylation gives the 3-(hydroxyaryl)-3,5-dideoxymucoinositols, whose stereochemistry is established by X-ray crystallography.
