Asymmetric Synthesis of 3,4-Annulated Cyclopentenones from Cycloalkenyl Ketones and Vinyl Carbamates by Diastereoselective Carbonyl Addition/Conrotatory 4π Ring Closure

1-Lithiated O-vinyl carbamates add with high induced diastereoselectivity onto enantiomerically pure cycloalk-1-enyl (1-dibenzylamino)alkyl ketones. Subsequent O-carbamoyl migration, followed by a torquoselective, antarafacial 4Ï ring closure, leads to homochiral 2-substituted bicyclo[n.3.0]alk-1-ene-2-ones.
Birchreduction of homotyramines with a syn-β-amino alcohol unit followed by acid treatment of formed dihydroanisole derivatives gives polysubstituted enantiopure cis-decahydroquinolines. The stereoselectivity of the process differs if the hydroxyl group is free or protected. The procedure allows the synthesis of 7-oxodecahydroquinolines embodying four stereogenic centres with the same relative configuration
