Reactivity of 1,5-Disubstituted-4-pentene-1,3-diones: Part I - Selective Bromination of 1-(2-Hydroxyphenyl)-5-phenyl-4-pentene-1,3-diones

1-(2-Hydroxyphenyl)-5-phenyl-4-pentene-1,3-diones (I) on buffered bromination afford 2-bromo-1-(2-hydroxyphenyl)-5-phenyl-4-pentene-1,3-diones (II) which undergo cyclodehydration with AcOH-H2SO4 to give 3-bromo-2-styrylchromones (III) while with ethanolic

Synthesis and Reactions of 1,5-Disubstituted 4-Pentene-1,3-diones

The title compounds (III) have been synthesised by the base-catalysed Baker-Venkataraman transformation of cinnamoyl and p-methoxycinnamoyl esters (II) of substituted 2-hydroxyacetophenones (I).The cyclodehydration of III with AcOH-H2SO4 affords 2-styrylc
