heterocyclic compounds which have shown significant biological activities. New nitro-2-styrylchromones have been synthesised by the Baker-Venkataraman method, and the structureelucidation was accomplished using extensive 1D (1H, 13C) and 2DNMR spectroscopic studies (COSY, HSQC and HMBC experiments).
