摘要:
Peroxide products of partial ozonolysis of (S)-(-)-limonene (ee 50%) in cyclohexane-methanol at 2-4A degrees C were treated with a solution of HCl in methanol, which led to the formation of a 4: 1 mixture of methyl [(1S)-2,4-dimethoxy-2,4-dimethylcyclohexyl]acetate and [(1S)-2,4-dimethoxy-2,4-dimethylcyclohexyl]acetaldehyde, each being represented by a single pair of diastereoisomers at a ratio of 3: 1.
