β¦ Synopsis
Experimental dipole moments of some disubstituted 9acridanones were compared to the vectorially and theoretically calculated values using CNDO/2 method. Results supported the existence of a presumed folding of these compounds with the prevalence of a quasiequatorial conformation.

Recent interest in the conformations of tropane and piperidine derivatives (l-9) prompts us to report our interpretation of the NMR spectra (10) of three tropanes that are substituted in the 2-and 3-positions (11). The
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.
