Four small type I collagen CNBr peptides containing complete natural sequences were purified from bovine skin and investigated by CD and 1H- and 13C-nmr spectroscopies to obtain information concerning their conformation and thermal stability. CD showed that a triple helix was formed at 10 degrees C

Two series of 2,4,6-tris(amino)-s-triazines were studied by 1 H and 13 C NMR. 15 N NMR had previously demonstrated hindered rotation of the acyclic amino substituents (NHallyl, NHpropyl) around the Ar -N bonds at room temperature. In the present work, 1 H and 13 C NMR studies showed that rotation is

A series of acetonides was obtained during the formal synthesis of deoxynojirimycin. The 1 H NMR spectra of these derivatives contain strongly coupled multiplets covering a chemical shift range of about 1 ppm. The spectra are severely complicated by second-order effects and were assigned by 2D NMR a

1-Aryl-4-carboxy-5-methyl-1,2,3-triazoles were prepared by the condensation of aryl azides with ethyl acetoacetate. The structures of these compounds were characterized by MS, IR and 1H and 13C NMR spectroscopy. The measured and calculated 13C chemical shifts of the aromatic carbons were compared.
