| Abstract: | 1. The preparation of a mono-O-cyclohexylidene derivative of l-ascorbic acid is described. 2. The new compound is shielded by the cyclohexanone group at C-5 and C-6 of the ascorbic acid molecule, while the double bond between C-2 and C-3 is kept intact. 3. The double bond of the new derivative is more resistant to oxidation than its parent compound. 4. Ascorbic acid is easily regenerated by mild acid hydrolysis. 5. The new derivative facilitates the synthesis of (14)C-labelled vitamin C. |
