A base‐promoted and highly selective temperature‐dependent tandem oxidation/decarboxylative cyclization of isothiocyanates and isatins has been developed. This method allows the chemodivergent synthesis of 4H‐benzo[d][1,3]thiazin‐4‐ones and 2‐thioxo‐2,3‐dihydroquinazolin‐4(1H)‐ones in moderate to high yields.

温度控制的碱促进的环化反应，用于合成2-氨基-4H-苯并[d] [1,3]噻嗪-4-酮和2-硫代-4-（3H）-喹唑啉酮

已开发出一种以碱为基础的，高度选择性的，温度依赖性的异硫氰酸酯和靛红串联氧化/脱羧环化方法。该方法允许以中等至高收率化学合成4 H-苯并[ d ] [1,3]噻嗪-4-酮和2-thioxo-2,3-二氢喹唑啉-4（1 H）-酮。
