Flav-4-ones on reaction with DMF/POCl3 gave 4-chloro-2-aryl-2H-chromene-3-carbaldehydes which on reaction with ethyl-3-aminocrotonate give under Hantszch reaction conditions ethyl-2-methyl-5-aryl-5H-chromeno[3,4-c]pyridine-1-carboxylates in good yields.
DDQ Oxidation of Flavan-4-ols - A New Method for Synthesis of Flavones
