Synthesis and antimicrobial activities of some isoxazolyl thiazolyl pyrazoles

A series of isoxazolyl thiazolyl pyrazoles 5a-d was synthesized by multi-step process, starting from 3-Acetyl-4-hydroxy-6-methyl-2H-pyran-2-one (dehydroacetic acid, DHAA) 1. DHAA 1 was easily converted to thiosemicarbazone 2 which on reaction with a-βromo
