[摘要]：A convenient method for synthesis of 5-chloro-2-aryloxazole-4-carbaldehyde 3 in moderate to good yields had been developed via the Vilsmeier reaction of readily available N-arylglycine 2 at 100 degrees C, provided a novel route for the construction of nitrogen heterocycles. A series of these compounds were synthesized by this method and optimization of conditions was performed. |
