The complete assignment of the H-1 and C-13 NMR spectra of eight thienyl-substituted chromenes was achieved by the concerted application of homonuclear (gs-COSY), H-1-detected heteronuclear one-bond (gs-HMQC) and long-range (gs-HMBC) gradient-selected correlation experiments. (C) 1998 John...
(DMSO-d 6); chemical shifts are expressed as δ values relative to Me4Si as standard; coupling constants (J) are given in hertz; multiplicity in 1H NMR is reported as singlet (s), broad singlet (br s), doublet (d), doublet of doublets (dd), triplet (t), quartet (q), and ...
DFT quantum chemical calculations of O–HO 1 H NMR chemical shifts of enol pairs, weighted by their proportions . as predicted by the relative free energies computed for them at the DFT level, agree well with experimental NMR chemical shifts. The main parameters affecting equilibrium constants ...
2). The stereochemistry of other products was determined on the basis of the similarities of the polarities and the 1H NMR and 13C NMR chemical shifts. Next, the synthetic utility of this methodology was further investigated. First, the gram-scale synthesis of 2aa, 2ah, and 2bb was ...
