“…Among the methodologies developed over the years for the synthesis of chromones, the most efficient are the Claisen condensation, Baker-Venkataraman and Kostanecki-Robinson methods [54,55]. The synthesis of halochromones can be carried out by applying the general methods for the synthesis of chromones using halogenated precursors or by halogenation of the chromone nucleus in a final stage.…”

“…Las -dicetonas (3) también se pueden obtener por una reacción de transposición de o-acetoxiacetofenonas (5), conocida como Reordenamiento o transposición de Baker-Venkataraman 79 (Wilson Baker 80 y Krishnaswamy Venkataraman 81 ). El reordenamiento se lleva a cabo en medio básico y la reacción siguiente (en medio ácido y calentamiento) permite obtener cromonas principalmente flavonas y otros benzopiranos usando otros medios de reacción.…”
