The carbon-13 NMR spectrum of gougerotin.
Gougerotin was isolated from Streptomyces gougerotii in 1962", its structure was established in 19692' and total syntheses were announced in 1972" and in 19754'. In the course of a soil screen we isolated gougerotin from an organism identified as Streptom}ices puniceus subsp. doliceus subsp. nov. (NRRL 11160). It was co-produced with the clazamycins''". The ultraviolet'' and proton magnetic res...

متن کاملCommunication 3 D 1 H – 13 C – 14 N correlation solid - state NMR spectrum
Nitrogen-14 (spin I = 1) has always been a nucleus difficult to observe in solid-state NMR and until recently its observation was restricted to one-dimensional (1D) spectra. We present here the first 3D H–C–N NMR correlation spectrum. This spectrum was acquired on a test sample L-histidine HCl H2O using a recently developed technique, which consists in indirectly observing N nuclei via dipolar ...
متن کاملQuantitative (13)C NMR analysis of lignins with internal standards.
Novel protocols for acquiring quantitative (13)C NMR spectra of lignins have been developed using the internal reference compounds 1,3,5-trioxane and pentafluorobenzene. Trioxane offers a convenient internal standard for collecting inverse gated proton decoupled (13)C NMR spectra for lignins, whereas pentafluorobenzene can be used to provide information on the amount of methine carbon using the...
متن کاملTwo-dimensional dynamic-director (13)C NMR of liquid crystals.
A novel nuclear magnetic resonance (NMR) experiment for facilitating the resolution and assignment of liquid crystalline (13)C NMR spectra is described. The method involves the motor-driven reorientation of the liquid crystalline director, in synchrony with the acquisition of a 2D chemical shift correlation spectrum. By monitoring in this fashion the (13)C NMR evolution of spins in the liquid c...
