Dehydroacetic acid (DHA) and its derivatives find wide applications in synthetic organic chemistry. The 8-aryloct-7-en-2,4,6-triones (DHA-triones), which are accessible by a multistep procedure commencing from the commercially available DHA, on reaction with 6-substituted benzothiazolylhydrazines led to regioselective synthesis of several new 5-(4-aryl-2-oxobut-3-enyl)-3-methyl-1-(6-substituted benzothiazol-2-yl)pyrazoles.
A novel and efficient synthetic method of benzo[f]chromen-1-ones and phenyl-4h-chromen-4-one through photooxidative cyclization of 6-[(E)-2-arylvinyl]-4H-pyran-4-ones and 6-[(1E,3E)-4-phenylbuta-1,3-dien-1-yl]-4H-pyran-4-one
