Notizen:
The positions of conformational equilibria in 1,5-, 1-6- and 1,8-dimethylperhydro-oxazolo[3,4-a]pyridines were determined by 1H NMR spectroscopy. The cis-(H-5, H-8a)-1,6-dimethyl-perhydro-oxazolo[3,4-a]pyridine. In contrast, r-1,t-6,t-8a-1,6-dimethylperhydro-oxazolo[3,4- a]pyridine preferred the cis-fused conformation. Three of the 1,8-dimethylperhydro-oxazolo[3,4-a]pyridines adopted the trans-fused conformations (with distortion of the system in the case of the r-1,c-8,c-8a derivative) and the r-1,c-8,t-8a-1,8-dimethyl derivative adopted the cis-fused conformation.
