One-Pot Green Synthesis of 2-Hydroxybenzoyl(cinnamoyl)methanes and 2-Styrylchromones Using Dual-Frequency Ultrasonication

Abstract: One-pot green synthesis of (2-hydroxybenzoyl)(cinnamoyl)methanes has been performed by reacting 2-hydroxyacetophenones with cinnamoyl chlorides using activated Ba(OH)2, followed by Baker–Venkataraman rearrangement assisted by dual-fre

REACTIONS WITH 2-METHYLCHROMONES

The reactivity of 2-methylchromones and their derivatives towards nucleophilic and electrophilic reagents, cycloaddition reactions, thiation, reactions with compounds containing active methylene group has been investigated.The IR, 1H-NMR and mass spectra of new chromone derivatives were discussed.Key words: 2-Methylchromones, cycloaddition reactions with compounds containing active methylene

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
