Synthesis and structure elucidation of three series of nitro-2-styrylchromones using 1D and 2D NMR spectroscopy

Magn Reson Chem. 2009 Oct;47(10):885-96. doi: 10.1002/mrc.2472.

Abstract

2-Styrylchromones, although scarce in nature, constitute a group of oxygen heterocyclic compounds which have shown significant biological activities. New nitro-2-styrylchromones have been synthesised by the Baker-Venkataraman method, and the structure elucidation was accomplished using extensive 1D (1H, 13C) and 2D NMR spectroscopic studies (COSY, HSQC and HMBC experiments).
