Abstract
1,4-Diazabicyclo[2.2.2]octane(DABCO)-catalysed reactions of selected chromone-3-carbaldehydes with acrylonitrile (or methyl vinyl ketone) have led to the formation of Baylis–Hillman adducts and, in some cases, novel polycyclic condensation derivatives; electron-impact and electrospray MS fragmentation patterns have been examined for selected products.

Abstract
Reaction of a series of chromone-3-carbaldehydes with methyl vinyl ketone under Baylis–Hillman conditions, using 3-hydroxyquinuclidine in chloroform or DABCO in 1-methyl-2-pyrrolidinone, affords unprecedented tricylic chromone derivatives which, depending on the conditions, may be accompanied by the normal Baylis–Hillman products or their respective tricyclic dimers.
