A facile route for the synthesis of 1-[5-hydroxy-3-methyl-1-(2-thiazolyl)-4-pyrazolyl)-1,3-butanediones from dehydroacetic acid

Article abstract of DOI:10.1080/00397919308011286

Thiosemicarbazone (1) of dehydroacetic acid (DHAA) reacts smoothly with α-haloketones to yield corresponding thiazolylhydrazones (2) of DHAA, which on refluxing in EtOH-AcOH rearrange to the title compounds (3).
