| Abstract | Introduction of an a-methylene-y-butyrolac tone unit at C-9 does not change the conformation of the bicyclononane ring system. However, NMR signals for H-I and H-5 and axia l H-7 protons are shi fted upfield and the signals for H-2 and H-4 protons are shifted down field. The signals for all ring carbons are shifted upfield. Spectral data show that the C(9)C( 10) bond of spirolactone is oriented towards the piperidine ring. |
