Abstract
The natural abundance ^13^C magnetic resonance spectra of reduced proaporphines are reported, with complete assignments based on peak multiplicity and empirical calculations of chemical shifts. The chemical shift values of Cโ8, Cโ12 and Cโ7 are found to be strongly diagnostic of the spiro carbon configuration.

## Abstract Carbonโ13 chemical shift assignments have been obtained for the naturally occurring __Cephalotaxus__ alkaloids, cephalotaxine, acetylcephalotaxine, harringtonine, isoharringtonine, drupacine and cephalotaxinone.
## Abstract The ^13^C NMR spectra were determined and signals assigned to the various carbons of the alkamines veracevine, germine and zygacine derived from steroidal alkaloids of the ceveratrum class. Assignment of signals was aided by analysis of the partially relaxed spectrum of cervagenine 9,12
## Abstract ^13^C n.m.r. spectra of some substituted isoxazoles have been examined to ascertain the reactive site in the metallation of 4โsubstituted 3,5โdimethylisoxazoles. The results obtained indicate that metallation occurred exclusively at the Cโ5 methyl.
C chemical shifts and ''P,l'C spin-spin coupling constants are reported for six model phosphinates and eight synthetic phosphinolipids. The complex spectra of the synthetic phosphinolipids could be assigned from increments and couplings derived from the model compounds. Based on these investigations
