The 13CNMR spectra of a series of nine taxane derivatives are reported. A detailed analysis of the assignments is presented. Observed long-range substituent effects are explained on the basis of the proximity of rings A and C in this type of molecules.

✦ Synopsis
Abstract
Carbon‐13 NMR spectra of a number of (−)‐ent‐kauranoids have been studied. An unambiguous selfconsistent assignment of resonances has been made by considering the changes in chemical shifts produced by the change of substituent(s).

## Abstract Carbon‐13 chemical shifts of three arylmethyl carbanions have been determined by changing solvents and counter ions. The charge distributions in the carbanions are discussed and compared with those obtained from the ^1^H chemical shifts.
## Abstract Assignments of the ^13^C NMR resonances for the toxic diterpenoids of ericaceous plants have been made. The data have proved to be a useful tool for the structural examination of the congeners. For example, the structure of asebotoxin‐VII to which a 6‐__O__‐acyl moiety had previously be
## Abstract Carbon‐13 NMR chemical shifts and one‐bond carbon–hydrogen coupling constants have been obtained at 15·09 MHz. The trends in the carbon chemical shifts obtained for the pyrazines parallel those of monosubstituted benzenes and 2‐substituted pyridines, except for the __direct__ effect of
