摘要

The phosphonic acid analog of the NSAID Diclofenac was efficiently synthesized via an Arbuzov reaction between 2-(2, 6-dichloroanilino) benzyl alcohol and trimethyl phosphite followed by TMSBr promoted dealkylation. Seven related phosphonic acids were synthesized using the same novel acid-catalyzed Arbuzov reaction as the key step.
