General description

4′-Chloroacetoacetanilide was trilithiated with lithium diisopropylamide and condensed with several aromatic esters, followed by neutralization, separate acid cyclization and rearrangements to yield 4-anilino-6-aryl-2H-pyran-2-ones. It undergoes three-component reaction with a mixture of aromatic aldehyde and 5-aminotetrazole to form N,7-diaryl-5-methyl-4,7-dihydrotetrazolo[1,5-a]pyrimidine-6-carboxamide.

Application

4′-Chloroacetoacetanilide was used in recombinant androgen receptor competitive binding assay for analysis of natural, synthetic and environmental chemicals.
