{ALF} Like 1,2-Cyclohexanedione, A14401, has been used by Ley's group in combination with trimethyl orthoformate and camphorsulfonic acid for the protection of trans-1,2-diols as cyclic diacetals. The method is particularly applicable to the carbohydrate field: Synlett, 793 (1996); J. Chem. Soc., Perkin 1, 2023 (1997). See also 9,10-Phenanthrenequinone, A11762.
