title: Domino reactions of 2-methyl chromones containing an electron withdrawing group with chromone-fused dienes.
abstract: Domino reactions of 2-methyl substituted chromones containing an electron withdrawing group at the 3-position with chromone-fused dienes synthesized a diverse range of benzo[a]xanthones and complicated chromone derivatives. These multiple-step reactions result in either two or three new C-C bonds without a transition metal catalyst or an inert atmosphere.
