Solid-Phase Synthesis of 2-Arylamino-5-(4-hydroxyphenyl)-1,3,4-thiadiazole Derivatives Based on Resin-Bound Acylhydrazines
摘要:
A highly efficient, solid-phase synthesis of 2-arylamino-5-(4-hydroxy-phenyl)-1,3,4-thiadiazole derivatives under mild conditions has been developed. The 1,3,4-thiadiazole derivatives were synthesized from resin-bound acylhydrazines in several steps, which gave 78-88% overall yields and excellent purities of the products.
