A phosgene and peroxide-free one-pot tandem synthesis of isatoic anhydrides involving anthranilic acid, boc anhydride and 2-chloro-N-methyl pyridinium iodide

Verma, Chhaya,Sharma, Somesh,Pathak, Arunendra

, p. 6897 - 6899 (2013)

A phosgene and peroxide-free approach for the synthesis of isatoic anhydrides has been described. The synthesis involves the carbamate formation with boc anhydride followed by in situ cyclization to afford the isatoic anhydride. The importance of this synthetic strategy is in the ease of operation, scalability and preparation from readily available raw materials.
