## Abstract The values and signs of ^13^C, ^1^H spin‐spin coupling constants in 1,6,6aλ^4^‐trithiapentalene and 1,6‐dioxa‐6aλ^4^‐thiapentalene have been re‐investigated. The contributions from second order effects in the spectra have been included in an iterative spectral analysis. The values found

The NOESY spectrum and vicinal coupling constants of t(4)-acetoxy-3,3-dimethyl-r(2),c(6)-diphenyl-Nacetylpiperidine suggest that the compound adopts a chair conformation with axial phenyl groups. The vicinal coupling constants of t(4)-acetoxy-r(2),c(6)-diphenyl-N-acetylpiperidine could be accounted

X-ray crystallographic analyses are reported for the two title compounds (8 and 9), of which the former crystallized in two modifications (8n and 8b). In all three structures, the pyranose rings have the %, (D) conformation and the substituents at C-l are axial and those at C-24-4 are equatorial. Th
