Mm. Heravi et al., Clay supported cerium(IV) reagents for oxidative deprotection of tetrahydropyranyl ethers under non-aqueous conditions, MONATS CHEM, 130(10), 1999, pp. 1253-1256
Primary and secondary tetrahydropyranyl ethers are efficiently converted to
the corresponding carbonyl compounds using clay supported [CS(NO3)(3)](2)C
rO4 and [Ce(NO3)(3)](3)HIO6 in dichloromethane.
