  摘要：

  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. (C) 2013 Elsevier Ltd. All rights reserved.
