Proton and Carbon Chemical Shift Assignments of Brodifacoum

We are making complete proton and carbon chemical shift assignments of both diastereomers of the potent vitamin K epoxide reductase (VKOR) inhibitor brodifacoum ((3-[3-[4-(4-bromophenyl)phenyl]-1,2,3,4-tetrahydronaphthalen-1-yl]-2-hydroxychromen-4-one). To resolve chemical shift degeneracies and overlap observed at 500 MHz, we are seeking 3 days of time on a high field (750 or 900 MHz) liquids instrument.
