Efficient syntheses of new polyhydroxylated 2,3-diaryl-9h-xanthen-9-ones

A large number of hydroxylated 2,3-diaryl-9H-xanthen-9- ones have been synthesised by two different approaches, starting either from 3-bromo-2-methyl-4H-chromen-4-one or from (E)-3-bromo-2-styryl-4H-chromen-4-ones. The former method involves Heck reactions between 3-bromo-2-methyl- 4H-chromen-4-one...
