¹H–¹³C n.m.r. chemical shift correlation

Functionalisation of saturated hydrocarbons. Part XI. Oxidation of cedrol, β‐ and γ‐eudesmol, sclareol, manoyl oxide, 1,9‐dideoxyforskolin, methyl trans‐dihydroiasmonate, and tetrahydrolinalool by the ‘Gif system’

“…Part). This and analysis of the NMR spectra led to the assignment of structures [29][30][31] (1.7, 1.4, and 1 YO, resp. ).…”

“…The J-modulation of the spin echo spectra [29] of 28 31 gives the multiplicities of the "C-NMR signals. From the number ofquaternary C, CH, CH,, and CH, groups, we can assess that a modification of the C skeleton is highly unlikely for 29 31 as compared to 28.…”

Synthesis of Chiral Ligands from Hydrindene Diols with a Consecutive Heterodomino Transformation as the Key Reaction Step

“…[28] For all compounds investigated, multiplicities of the 13 C NMR spectroscopic resonances were assigned by the SEFT technique. [29] Chemical shifts in the 1 H NMR spectra are expressed downfield from TMS with the use of the residual nondeuterated solvent as an internal standard (CDCl 3 1 H NMR, 7.26 ppm; C 6 D 6 1 H NMR, 7.15 ppm). 13 C NMR chemical shifts are reported relative to CDCl 3 or the C 6 D 6 triplet centered at δ = 77.0 ppm and 128.0 ppm, respectively.…”

Mild Protocols for Generating Molecular Complexity: A Comparative Study of Hetero‐Domino Reactions Based on the Oxidant and the Substitution Pattern

“…For all compounds investigated, multiplicities of 13 C resonances were assigned by the SEFT technique. [42] Electron spray mass spectra were obtained in instances where electron impact and chemical ionization failed to produce molecular ions. Mass spectra acquired in the positive-ion mode under electron spray ionization (ES + ) using a mobile phase of methanol, are abbreviated as ESIMS (MeOH).…”
