Özet

The absol. configuration of a Ciramadol analogue obtained from (-)-menthone is established by H-1-NMR-, simulated NMR-, COSY-90-, and NOE-measurements. The final compound 2-(alpha-1-pyrrolidino)benzyl-4-isopropyl-1-methyl-cyclohexan-3-one (4b), e.g., has 1R,2S,4S,11S-configuration due to stereoselective Michael-type addition of pyrrolidine to the pertinent benzylidene intermediate 3.
