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.
NSAID双氯芬酸的膦酸类似物是通过2-(2,6-二氯苯胺基)苄醇与亚磷酸三甲酯之间的Arbuzov反应有效合成的,然后通过TMSBr促进的脱烷基反应。使用相同的新型酸催化Arbuzov反应作为关键步骤,合成了七个相关的膦酸。
