Carbon‐13 nuclear magnetic resonance spectra of phenycyclidine analogs

Abstract Natural abundance carbon‐13 chemical shifts are reported for the hydrochloride salts of phencyclidine ( 1a ) and sixteen analogs. The signals are assigned on the basis of chemical shift theory, SFORD multiplicities, signal intensities, and comparisons with model compounds. In addition to its forensic value, the data suggests that the solution conformations of the analogs are similar to that of phencyclidine hydrochloride.
