SWIM sees a couple of obstacles...
1. The paper by Quelet says that dehydrochlorination is done using pyridine. If we had pyridine in the first place, then eugenol --> safrole would be a much better idea.
2. We need to buy/make 1-propanal.
Once SWIM saw the dreaded 'p' word (pyridine) in the article, her/his heart just dropped
. Is there any other way to dehydrohalogenate that chloropropyl group?
