Chromone studies. Part 15. Formation and condensation of Baylis- Hillman adducts in DABCO-catalysed reactions of chromone-3-carbaldehydes with acrylonitrile.
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.

The Journal of Chemical Research is a monthly journal which has a broad international authorship and publishes research papers and reviews in all branches of experimental chemistry.
Established in 1977 as a joint venture by the British, French and German chemical societies it maintains the high standards set by the founding societies. Each paper is independently peer reviewed and only carefully evaluated contributions are accepted.
Recent papers have described new synthetic methods, new heterocyclic compounds, new natural products, and the inorganic chemistry of metal complexes.
