A simple, efficient, and cost-effective method has been developed for the synthesis of some cinnamic acid derivatives in moderate to high yields (63-86%) by a one-pot condensation reaction of benzaldehyde and aliphatic carboxylic acids in the presence of sodium tetraborate and benzyltriethylammonium chloride, and N-methyl-pyrrolidinone as solvent. The reaction requires high temperatures (reflux at 180-190°C) and strong basic conditions, which have been generated by pyridine and 4-dimethylaminopyridine added to the reaction medium.
A novel direct boron-mediated synthesis of cinnamic acids from aromatic aldehydes and aliphatic carboxylic acids

experimental part, p. 987 - 991 (2011/06/21)
Cinnamic acids have been prepared in 64-85% yields by a new direct synthesis from aromatic aldehydes and aliphatic carboxylic acids in the presence of anhydrous sodium tetraborate and lithium chloride, bases as pyridine (Py) and 4-dimethylaminopyridine (DMAP), and N-methyl-2-pyrolidinone (NMP) as solvent, at reflux (180-190°C), for 8-12 hours. Without sodium tetraborate-lithium chloride this reaction is not possible.
