Stereospecific synthesis of polyfunctionalized carbacephams induced by titanocene(III) chloride

Enantiomerically pure N-substituted epoxyalkene-2-azetidinones reacted with titanocene monochloride to give stereospecifically polyfunctionalized bicyclic β-lactams. Four isomeric epoxyaldehydes 2 reacted with TiCp2- Cl to give exclusively the respective carbacephams 7 while under the same reaction conditions the epoxyesters 1, which are more hindered for an intramolecular addition, gave the cyclization products 6 (only two isomers) and/or the elimination products 5 (all isomers).
