The complete assignment of the 1H and 13C NMR chemical shifts, from 2D techniques and spectra recorded at 500 MHz, for 3-substituted norbornanones with Cl, Br, I, SMe and SeMe substituents at endo and exo positions and 3-exo-hydroxynorbornanone is reported. The observed 1H chemical sh...
The invention discloses a method to generate and analyze NMR chemical shift based binary fingerprints for virtual high throughput screening in drug discovery. Further, the invention provides a method to analyze NMR chemical shifts based binary fingerprints that has implications for encoding several prop...
