usually cinnamic acids derivatives are easily synthetized from malonic acid and aromatic aldehydes in pyridine/piperidine mixture as catalyst but such mixture smells like hell and it is pretty noxious. so, with the aim to avoid such harmfull reagents does someone has any ideea how could i proceed to synthetized the above named compound?
what about na2co3 and a phase transfer catalyst? is it a reliable idea?
have a nice day guys and thank u in advance for any idea
