Khosropour, Ahmad Reza published the artcileSynthesis of trans-cinnamic acids from aryl aldehydes and aryl aldehyde bisulfite adducts with malonic acid using piperazine, Category: catalysis-chemistry, the publication is Journal of Chemical Research (2005), 364-365, database is CAplus.
Piperazine as a new reagent for the condensation of aryl aldehydes and their bisulfite adducts with malonic acid are described which afford the corresponding cinnamic acids in excellent yields and short reaction times in the absence of solvents under microwave irradiation
