Structural characterization of strained oxacycles by 13C NMR spectroscopy
(Arkat USA, 2011-02)
The 1H and 13C NMR data of a series of epoxy-and epidioxy-bridged tetrahydropyran derivatives containing the same basic carbon skeleton, are reported. 13C NMR spectroscopy was shown to be useful for structural determination ...
Complete ¹H and 13C NMR structural assignments for a group of four goyazensolide-type furanoheliangolides
(Sociedade Brasileira de Química, 2012)
Four goyazensolide-type sesquiterpene lactones - lychnofolide, centratherin, goyazensolide and goyazensolide acetate - were thoroughly studied by NMR experimental techniques. ¹H NMR, 13C NMR {¹H}, COSY, HMQC, HMBC, J-res. ...
COMPLETE H-1 AND C-13 NMR STRUCTURAL ASSIGNMENTS FOR A GROUP OF FOUR GOYAZENSOLIDE-TYPE FURANOHELIANGOLIDES
(SOC BRASILEIRA QUIMICASAO PAULO, 2012)
Four goyazensolide-type sesquiterpene lactones - lychnofolide, centratherin, goyazensolide and goyazensolide acetate - were thoroughly studied by NMR experimental techniques. H-1 NMR, C-13 NMR {H-1}, COSY, HMQC, HMBC, ...
New Trends in Field-Cycling NMR Technology
(Royal Society of Chemistry, 2018)
This chapter discusses different aspects related to the evolution and current state of fast field-cycling NMR technology. Technical advances affect NMR in two main ways: by extending and improving the capabilities and ...

Spectroscopic methods for the identification of sesquiterpene lactones
(Springer, 2018)
The most widely used spectroscopic methods for the identification ofsesquiterpene lactones are discussed. The most distinctive and characteristic signals in the UV, IR, MS, 1H-MNR and 13C-NMR spectra are discussed. In ...
Combined (13)C NMR and DFT/GIAO studies of the polyketides Aurasperone A and Fonsecinone A

13C-NMR spectroscopy of para-substituted benzylideneacetones. I. Long distance electronic effects
(Marcel Dekker Inc., 1997)
Para-benzylideneacetones present a characteristic long distance charge transfer pattern, where the olefinic bridge (CH=CH) and the aromatic ring (Ph) carbon centers are perturbed according to the nature of the para-substituent ...
Succinyl-β-cyclodextrin: Influence of the substitution degree on albendazole inclusion complexes probed by NMR
(Elsevier Science, 2018-11)
Succinyl-β-CD derivatives were obtained by green synthesis with degrees of substitution (DS) 1.3 and 2.9. The spray-drying technique was used to obtain albendazole (ABZ):succinyl-β-CD inclusion complexes. Phase solubility ...
