A one pot synthesis of an array of angularly linked tri-heterocycles with coumarin, benzofuran and furan rings is described. This high yielding synthesis is achieved by the reaction of various 4-bromomethylcoumarins with furyl o-hydroxyphenyl ketones involving benzylic nucleophilic displacement and intramolecular aldolization. All the compounds have been tested in vitro for their anti-microbial activity against Micrococcus aureus, Pseudomonas chinchori, Asperigillus fumigatus and Penicillium wortmanni at 100, 50, and 25 microg ml(-1) concentrations. Chloro groups in the benzofuran ring enhanced the activity.
