The reaction of 3-formylchromones with aminoheterocycles was investigated. A simple and flexible general procedure for annulation of 5-(2-hydroxybenzoyl) pyridines was proposed. The best reaction conditions were found to be heating the reaction mixture in DMF in the presence of Me3SiCl as a promoter and water as scavenger. Georg Thieme Verlag Stuttgart.
