Microwave assisted synthesis of 1-(2-hydroxyphenyl)-5-phenyl pent-4-ene-1,3-diones and their conversion to 2-styryl chromones

A simple and efficient method has been developed for the rapid synthesis of 1-(2-hydroxyphenyl)-5-phenyl pent-4-ene-1,3-diones 3a-g in a single pot reaction under microwave irradiation. These β-diketones are further converted into 2-styryl chromones again

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
