The reaction of chromone and its C-2 and C-3 substituted methyl derivatives was studied.New compounds in the systems of 2-pyrazoline (3, 14), 1,3-butanedione (9), pyrazole (4, 10, 11, 15) and chromone (7) were obtained.Methyl groups at C-2 and C-3 position desactivate the chromone system towards thiosemicarbazide.
