Abstract The 13CNMR spectra of the erythro and threo forms of representative members of the 8-O-4′ type of neolignans were recorded and the signals assigned. Based on these assignments and on the comparison with previously reported 1H NMR data, the most probable conformations for the above mentioned stereoisomers are suggested.
