A new synthesis for 2,3-diarylxanthones is described. This was accomplished by aldol condensation of 3-bromo-2-methylchromone with benzaldehydes leading to the formation of 3-bromo-2-styrylchromones, followed by Heck reaction with styrenes. Georg Thieme V

A large number of hydroxylated 2,3-diaryl-9/i-xanthen-9ones have been synthesised by two different approaches, starting either from 3-brom.o-2-m.elhyl-4H-ch:rom.en-4-one or from. (E)-3-brom.o-2-styryl-4H-chrom. en-4-ones. The former method involves Heck r
