Complete assignment of the ¹H NMR data and reassignment of ¹³C NMR data of four spongian diterpenes

Marine natural products

“…525 NMR data for spongia-16-one, 526,527 dendrillol-1 and -2, 528-530 and aplyroseol-6, 531 have been reassigned using a 800 MHz spectrometer aer inconsistencies between the legacy spectroscopic data for these common spongian diterpenoids was noted. 532…”

Identification of compounds from terrestrial dissolved organic matter toxic to cyanobacteria

“…Details on the pulse program, scan number, relaxation delay, pulse width, spectral width, and spectra resolution for NMR experiments are found in Hayton et al, (2017). The 1 H and 13 C chemical shifts were referenced to the residual proton and carbon resonances in d 6 -DMSO (Cambridge Isotope Laboratory, Inc.) at δ H = 2.50 and δ C = 39.52 ppm.…”
