The synthesis of relevant renewable aromatics from bio‐based furfural derivatives and cheap alkenes is carried out by using a Diels‐Alder/aromatization sequence. The prediction and the control of the ortho/meta selectivity in the Diels‐Alder step is an important issue to pave the way to a wide range of renewable aromatics, but it remains a challenging task.
