Reaction Steps

Following the process of Example 13, 10-ethoxy-6,10-dimethylundec-3-en-2-one is converted into methyl 11-ethoxy-3,7,11-trimethyldodeca-2,4-dienoate. Reaction of 10-ethoxy-6,10-dimethylundec-3-en-2-one with the carbanion of diethyl carboethoxymethylphosphonate yields ethyl 11-ethoxy-3,7,11-trimethyldodeca-2,4-dienoate.
