Resumo(s)
Two series of novel
propargyloxychromones were
designed and synthesized. Both
chromone derivatives were used
as substrates in MW-assisted
intramolecular Diels-Alder
reactions, affording
chromeno[3,4-b]xanthones and
(benzo[c]chromenyl)chromones.
This is the first report involving
chromone derivatives in
intramolecular Diels-Alder
reactions for the synthesis of
new oxygen heterocycles,
namely xanthones and flavones.
