The 13C NMR spectra of several 1-(2-hydroxymethylcyclopentyl)and 1-(2-hydroxymethylcyclopentylmethyl)uracils and 5halouracils (X ΒΌ Cl, Br or I) were fully assigned with the aid of one-(13C, 1H-1H NOE, DEPT) and two-dimensional (HMQC) NMR experiments.

β¦ Synopsis
The 13C N M R spectra of eight biologically interesting benzofuranimidazoles were measured and assigned on the basis of 13C-l H (short-and long-range) correlated spectra

We report the 13C NMR chemical shifts of some active quinolones against Plasmodium falciparum, namely 3-amino-9-phenyl-1H-pyrazolo [3,4-b]quinolones and 2,4-diamino-10-phenylpyrimido[4, 5-b]quinolones. They were characterized and assigned on the basis of 13CΓ1H (short and long-range) correlated spec
13C NMR chemical shifts were measured in for Γuorocarbonyl compounds. Sulfonic DMSO-d 6 derivatives display 4J(C,F) coupling constants for carbonyl groups which are also obtained from non-sulfonic derivatives when they are recorded in acidic solution.
