Hydroxy-2-styrylchromones 5a-i were prepared by debenzylation of benzyloxy-2-styrylchromones 3a-i, which were synthesised by the Baker-Venkataraman method. The last step of this method, the cyclodehydration 5-aryl-3-hydroxy-1-(2-hydroxyaryl)-2,4-pentadien

The first reported 1,3-dipolar cycloaddition of 2-styrylchromones with diazomethane afforded 4-aryl-3-(2-chromonyl)-2-pyrazolines. However, 3-aryl-4-(2-chromonyl)-1-pyrazolines have been also found as minor products of this reaction. These two series of p
