inositols by blocking all but one hydroxyl group, converting the free hydroxyl group into its S -methyl dithiocarbonate, and treating it with tributylstannane. Suitable blocking-groups are methyl, benzyl, and methylthiomethyl ethers, and acetals. One cyclohexanepentol was prepared by the reductive deamination of an aminodeoxyinositol.
Photooxygenation of 1,4-cyclohexadiene 3 followed by reduction with LiAlH4 or thiourea gave (25/1)-cyclohex-3-ene-triol 7a. trans-Hydroxylation of triol 7a with three different methods afforded both of proto-quercitol la and vibo-quercitol 2a.
