摘要

Efficient and green syntheses of heterocycles are of great importance. In this work, we have demonstrated the synthesis of benzo [d] thiazoles and benzo [d] oxazoles using 2- acylpyridazin-3 (2H)-ones as acyl transfer agents under transition-metal-free and eco- friendly conditions. It is worthy to note that the reaction is efficient, green, and economical, and will find several applications in organic synthesis, medicinal chemistry, and industrial ...
