Chromone-3-ylmethyl aryl ethers with unsubstituted orthopositions have been found to undergo a novel domino [1,3]-[1,3]-rearrangement to give 4′-hydroxyhomoisoflavones under thermal conditions while the para-substituted ethers lead to 2′-hydroxyhomoisofla

That hydrolysis of benzopyranobenzopyrylium derivatives 1 includes a double-bond shift giving derivatives 5 of 3-(2-hydroxybenzyl)benzopyran-4-ones has been confirmed.Chromones like 5 are related to the 7H-benzopyranobenzopyryliu
