摘要

Abstract A convenient two step protocol preparation of the ortho-alkylated (by secondary substituent with the carbomethoxy group at the end of alkyl chain) aromatic carboxylic acids 6 from benzoic acids anilides 1 was developed, which exploited the reductive alkylation of phthalides 4 with silyl vinyl ethers 5a–b or silyl ketene acetals 5c–g as a key step, is described.
