Abstract

The 1H/15N HMBC experiment at 15N natural abundance using pulsed field gradients is a useful tool for chemical shift assignment and structure elucidation. This experiment assisted in the identification of regioisomers that could not be distinguished with conventional 1H/1H nuclear Overhauser or 1H/13C correlation NMR experiments. The natural abundance 15N gradient-enhanced HMBC experiment was easily implemented, provided high-quality spectra and readily distinguished nitrogen-containing regioisomers. This experiment can aid in structure elucidation when traditional 1H and 13C experiments fail to provide unique structural assignment. © 1998 John Wiley & Sons, Ltd.
