^aAssignments based on analysis of 2D NMR spectra.

^bData (δ) measured at 500 MHz; brs = broad singlet, dd= doublet of doublets, dt = doublet of triplets. J values are in Hz and are omitted if the signals overlapped as multiplets. The overlapped signals were assigned from HSQC and HMBC spectra without designating multiplicity.

^cData (δ) measured at 125 MHz; CH₃, CH₂, CH, and C multiplicities were determined by HSQC experiment.
