Abstract Baylis–Hillman reactions of pyridine-2- and quinoline-2-carbaldehydes with chromone derivatives, using tetramethylpropylenediamine in tetrahydrofuran (THF)–H2O, afford convenient access to adducts, cyclization of which leads to the corresponding tetra- and pentacyclic products. The relative efficiencies of thermal and microwave-assisted cyclization approaches have also been examined.
