Abstract

Two‐dimensional nitrogen–carbon NMR correlation spectra have been derived by a new reconstruction technique based on standard two‐dimensional HMQC and HMBC spectra, and operating with natural ^15^N and ^13^C isotopic abundances. Compared with conventional three‐dimensional spectroscopy in which ^15^N and ^13^C spins must be present in the same molecule, the reconstruction method offers two orders of magnitude improvement in sensitivity. Vitamin B‐12 serves as an illustrative example. Copyright © 2007 John Wiley & Sons, Ltd.

## Abstract The ^15^N‐NMR spectra of vitamin B~12~ analogues obtained in fully ^15^N‐labelled form have been measured by direct and inverse (^15^N, ^1^H) correlated spectroscopy. All resonances, except those of the NH~2~ groups, have been assigned to individual N‐atoms. The influences on δ (N) are
