is there an easy way to synthesize gingerol?
Check a publication by Michel Martin and Philippe Guibet in
Chirality, Volume 3, Issue 2 (p 151-155) at your local chemistry library or
here if you have a subscription. There are other syntheses as well but this one appeals to me because of the cycloaddition chemistry in the first step.
I would call this a relatively easy total synthesis, but it depends on your skill level. If you are an experienced synthetic organic chemist it might take you a month. If you are a student or not an experienced chemist then this synthesis will be well beyond you. Why are you trying to make gingerol? Lots of people sell it.
