THE TOTAL STEREOSELECTIVE RETRO MASS SPECTRAL SYNTHESIS OF (+/-)-EMETINE

A new route to (+/-)-emetine (18) via the Michael addition product (4A) is described.Addition of 3,4-dihydro-6,7-dimethoxy-1-methylisoquinoline (3) to the α,β-unsaturated ester (2) afforded 2-(3',4'-dihydro-6',7'-dimethoxy-1'-isoquinolinylmethyl)-3-methoxycarbonyl-1,2,3,6,7,11b-hexahydro-9,10-dimethoxybenzoquinolizin-4-one (4A) which was converted to (+/-)-emetine in 6 steps.
