✦ Synopsis

London SW3 6LX, UK CNMR data for a series of natural and semi-synthetic ar-hydroxy-and -metho--substituted Strychnos alkaloids are presented and are used to determine substituent-induced chemical shift (SCS) values for the various substitution patterns. 13 R1 H R3 20 alkaloids have been examined. The full range of com-R* cH3 R2 0 5 H 10 19 Rp-&)

## Abstract Carbon‐13 NMR signal assignment of a number of polyoxygenated triterpenes of the olean‐12‐ene and urs‐12‐ene series, carried out by considering the changes in chemical shift produced by the change of oxygenation pattern(s), and using methyl oleanolate as a model, are reported.

## Abstract The ^13^C NMR spectra of several 2‐substituted imidazoles and benzimidazoles have been measured. The substituent was CH~3~, COOH and CONHR, where R = H, __n__‐Bu, __p__‐tolyl or __m__‐chlorophenyl. Carbons 4 and 5 in the imidazoles and the carbon pairs 8/9, 4/7 and 5/6 become equivalent

## Abstract ^77^Se and ^13^C chemical shift of 19 1,2,3‐selenadiazoles are discussed in terms of substituent effects and conforma‐tional behaviour of the molecules. It is shown that the ^77^Se chemical shifts of such compounds are suitable tools for chiral discrimination in diastereomeric compounds

13C NMR data are presented for 31 variously substituted derivatives of 9acridanone and 15 derivatives of 9-thioacridanone. Unexpected shifts are explained in terms of hydrogen bonding or tautomeric equilibria.
