## Abstract The preparation, isolation and characterization by proton and ^13^C NMR of the four possible atropisomers of __meso__‐tetra(2‐methoxy‐1‐naphthyl)porphyrin is described. Chemical shift differences due to atropisomerization effects are observed in the porphyrin and naphthyl rings. Compari
## Abstract Using the carbon assignments of bleomycin A~2~ as well as those of a series of model compounds, the ^13^C NMR assignments of the antitumor antibiotic tallysomycin (TLM) have been made. With the aid of the carbon assignments the metal binding properties of the new antibiotic toward Zn(II
C Chemical shifts are reported for the ruthenium(II) tris complexes of thirteen 2,Z-bipyridyls and three 1,lO-phenanthrolines and for the osmium(]") bris complexes of five 2,2'-bpyridyls. Chelation induced shifts -&3 are discussed in terms of models for n back-bonding. -C NMR is shown to be a conven
Chiral synthons containing either 13Cor 15N-labelled glycine were prepared. The 13C and 15N NMR spectra of the Ni(II) complex of the Schi † base of (S)-2-(N-benzylprolyl)aminobenzophenone and 13C-1-, 13C-2or 15N-labelled glycine were measured and assigned. The observed splitting of the carbon signal
